Sometimes people who give an excellent talk do not send the manuscript by the deadline. However, this time, thanks to the punctuality of all the participants, we have this excellent volume for the workshop on mass losing pulsating stars and their circumstellar matter prepared in time. Almost all of the oral presentations including the summary are collected in this volume. We regret that we cannot put in this volume a few posters that we failed to receive before the editorial work. The workshop was planned as a small meeting with less than fifty attendants because the city of Sendai was far from the most of the active institutions. However, the number of submitted papers exceeded the SOC's expectation; many interesting contributions had to be scheduled in the poster session. Still, the oral sessions were so tight that many participants might have felt frustrated for the shortage of discussions. The organizers of the workshop have to apologize to the attendants for the inconvenience caused from such a happy underestimate about the size of the workshop.

Available in PDF, EPUB and Kindle. Book excerpt: The organization of this Symposium had its beginnings at the International Astronomical Union General Assembly in Grenoble in 1976. The initial "rounding up" of the Scienti fic Organizing Committee was begun by Drs. Snow and Swings; most of us who became the eventual organizing committee met a few times during the Assembly and formulated the essential outlines of the meeting. Extensive correspondence with all the committee subsequently established the program. The idea was to bring together both observers and theoreticians to discuss the stellar winds and mass loss rates and their effects on evolutions of O-type stars. On the observational side, there are now spectroscopic data from the far UV to the near IR regions concerning the stellar winds. There is also information about the free-free emission in the wind from the IR and radio portions of the spectrum. Fortunately, these different detection methods give more or less the same mass loss rate for the one star, s Pup" which has been observed at all wavelengths. One of the intents of the first three sessions of this Symposium is to outline the eXisting data on mass loss rates as it per tains to the O-type stars.

This book was released on 2012-12-06 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamental unsolved problems of stellar astrophysics include the effects of angular momentum on stellar structure and evolution, the nature and efficiency of the processes by which angular momentum is redistributed within and lost from stars, and the role that stellar rotation plays in enhancing or driving stellar mass loss. There appears to be a qualitative change in the nature and efficiency of these mechanisms near spectral type FO: hotter (more massive) stars typically retain more angular momentum at least until they reach the main sequence, while cooler stars typically spin down quickly. For the hotter stars, recent work suggests a strong link between the type of pulsation behavior, the mass loss rates, and the rotation velocity. If the same mechanisms are able to drive mass loss from the main sequence A stars, as has recently been proposed, then the current interpretations of a number of observations will be drastically affected: e. g. the ages of clusters may be incorrect by up to a factor of two, and the surface abundances of isotopes of He, Li and Be may no longer give constraints on cosmological nucleosynthesis. There are also effects on the evolution of the abundances of elements in the interstellar medium and on the general evolution of populations of stars. Thus the questions of the mechanisms of angular momentum and mass loss of stars more massive than the sun is important not only for stellar studies but for the foundations of much of modern astrophysics.

Available in PDF, EPUB and Kindle. Book excerpt: Following a successful coup against the tyrannical Syndicate, the leaders of the rebel Midway Star System work to forge a government free enough to please its citizens yet strong enough to secure power. But in a world where former rulers have become new foes, an alien threat to humanity may turn old adversaries into uncertain allies. President Gwen Iceni believes Midway is their only defense against the enigmas. Syndicate training taught her self-preservation in a crisis, yet she’s determined to fight for the star system’s fate…even if it means joining forces with another former Syndicate CEO—and an officer of the hated Alliance. Despite General Artur Drakon’s misgivings, he partnered with Iceni to overthrow Syndic forces. Now, with an enigma fleet menacing their hard-earned independence, he can ill afford to trust her—or lose her support. But in the back of his mind, there are three words that describe someone who confides in a Syndicate CEO: Stupid. Betrayed. Dead.

Download or read book Pulsation and Mass Loss in Stars written by R. Stalio and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stellar mass loss is an essential part of the cycling of material from the interstellar medium into stars and back, and must be understood if we are to model processes on galactic to cosmological scales. The study of stellar winds and the effects of stellar mass loss has reached a particularly exciting stage where observational capabilities are increasingly able to provide interesting constraints on models and theories. Recent resu1ts from theoretical and observational work for both hot and cool stars with substantial winds have led to the suggestion that a combination of pulsation with other mechanisms makes for particularly efficient mass loss from stars. This provided the original motivation for the organization of this workshop. The conference was organized along relatively conventional lines according to the types of objects being scrutinized. However the true unity of the proceedings comes from the interplay of the mechanisms involved. For example, for the cool, luminous Mira variables, pulsation leads to shock waves that extend the atmosphere, enhancing dust formation; radiation pressure on dust drives the wind, cooling the atmosphere and in some cases suppressing the shocks. Similarly for the Be stars, both pulsation (in this case, non-radial) and radiation pressure (due to UV resonance lines) are expected to be important, and this expectation is at least qualitatively borne out by the observations.

This book was released on 2012-12-06 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: In May 1986 a two-day workshop on Physical Processes in Comets, Stars and Active Galaxies was held at the Ringberg Castle near Lake Tegernsee, and this rather unusml. l collection of topics needs a few words of explanation. When we first thought of organizing a workshop on such a large variety of astrophysical objects our main motivation was to honor Rudolf Kippenhahn and Hermann Ulrich Schmidt on the occasion of their 60th birthdays, and we planned to cover at least a fraction of their fields of active research. We then realized immediately that despite the fact that the objects are so different, the physical processes involved are very much the same, and that it is this aspect of astrophysics which governed the scientific lives of both of our distinguished colleagues and friends and allowed them to make major contributions to all those fields. Apparently this viewpoint was shared by many colleagues and it was therefore not surprising that in response to our invitation everybody who had been invited agreed to come and to present a talk. The workshop then turned out to be a real success. In contrast to highly specialized conferences, fundamental problems as well as very recent devel opments were discussed and the participants appreciated the opportunity to exchange ideas.

This book was released on 2012-12-06 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this Symposium, researchers specializing in pulsation, rotation, magnetic fields and stellar winds are brought together for the first time in order to broaden our understanding of O and B stars. Thanks to advances in digital spectroscopy, new types of pulsating B stars have been discovered. The pulsations can be understood in terms of the recent revision of metal opacities, but the effects of rapid rotation and magnetic fields need further study. Observations in the UV and X-ray regions demonstrate that many B and Be stars show other activity, besides pulsation which is not yet understood. The reason for the enhanced mass loss in Be stars is a question which dominates the Symposium and which remains unanswered, although it is surely to be found in activity at or near the photosphere coupled with rotation. It is shown that the geometry of the circumstellar envelopes around Be stars is indeed a flattened disk as they can now be optically resolved. The variability of radiatively-driven winds from O and B stars are likely related to the rotation of the star. This underlines the central theme of the book: that the various phenomena seen in these stars cannot be studied in isolation.

In the aftermath of her older sister's death, sixteen-year-old Carrie is taken under the wings of her sister's friends, and finds herself forsaking the science nerds of her former life and slipping into a daze of cheap beer and recreational drugs. Carrie - a talented guitar player and obsessive tracker of the coming Vira comet - is partying hard and fooling around with boys she doesn't even like, even though she's desperate for a boyfriend. Her mother, enveloped by grief at the loss of her eldest child, has retreated to a monastery in the Catskills that requires a vow of silence. With her family splintered apart, Carrie is overcome at times by uncontrollable rages and her father decides to send her to a boot camp for wayward teens. Compounding the shame, and to her horror, she is forced to wear work boots and a hard hat - boy poison. Then she meets Dean, a fellow musician and refugee from his own dark past. Throughout the summer Carrie learns more about Dean, about her sister's death, about her own family's past, and about herself...as well as about the Bee Gees, disco and the difference between wood and sheet-rock screws. Through love, music and her precious comet - and no small help from Lou Reed - Carrie fumbles her way through the complex web of tragedies and misunderstandings, to the heart of who she is and who she wants to be.

Available in PDF, EPUB and Kindle. Book excerpt: This book identifies the 'lost stars' of Bayer, Lacaille, Flamsteed, and other pioneering astronomers of the 17th and 18th centuries, and explains how and why these stars seem to have disappeared from modern star catalogues and atlases. In a style that will appeal to the novice as well as the seasoned astronomer, the author provides an introduction to early modern astronomy. The book reviews the composition and history of the 88 constellations recognised by the International Astronomical Union. In an account for each constellation the author includes a synopsis, in chart form, that tells the reader at a glance how many lettered or numbered stars there are in the constellation, the magnitude and catalogue numbers for those stars, and who first lettered or numbered each star. The author then describes the stars that have been 'lost' or mislabelled and explains, in detail, their troublesome status.
