Assessment of Options for Extending the Life of the Hubble Space Telescope
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309095301
Category : Science
Languages : en
Pages : 160
Book Description
The Hubble Space Telescope (HST) has operated continuously since 1990. During that time, four space shuttle-based service missions were launched, three of which added major observational capabilities. A fifth â€" SM-4 â€" was intended to replace key telescope systems and install two new instruments. The loss of the space shuttle Columbia, however, resulted in a decision by NASA not to pursue the SM-4 mission leading to a likely end of Hubble's useful life in 2007-2008. This situation resulted in an unprecedented outcry from scientists and the public. As a result, NASA began to explore and develop a robotic servicing mission; and Congress directed NASA to request a study from the National Research Council (NRC) of the robotic and shuttle servicing options for extending the life of Hubble. This report presents an assessment of those two options. It provides an examination of the contributions made by Hubble and those likely as the result of a servicing mission, and a comparative analysis of the potential risk of the two options for servicing Hubble. The study concludes that the Shuttle option would be the most effective one for prolonging Hubble's productive life.

The Biggest, Baddest, Coolest Stars

ISBN:
Category : Astronomy
Languages : en
Pages : 304
Book Description
Cool evolved stars are among the brightest point sources in the infrared sky, and contribute significantly to the interstellar dust of galaxies. They are in a short-lived but important stage of stellar evolution, characterized by pulsations, dust formation, and the production of expanding circumstellar shells. This conference highlighted the physics of evolved cool stars in relation to their stage of evolution, atmospheric structure and dynamics, stellar winds, and associated dust formation. The conference was held at the Millennium Centre near the campus of East Tennessee State University in Johnson City, Tennessee, in July 2007. It brought together astronomers, both professional and amateur, who are working on different aspects of cool star research. These included dust theorists, numerical modelers, and experts in observations at different wavelengths. The result of the meeting was a more complete picture of these stars, which is summarized in this volume. Several recent developments motivated the need for this conference. Current hydrodynamic models of evolved stars are now able to reproduce the optical/UV spectra of such stars. However, simultaneous modeling of the infrared spectrum has proven difficult. Also, adding dust to such modeling is problematic because of the complicated physics of dust formation, destruction, and emission in these dynamic environments. Furthermore, the exact evolutionary relationship between the various types of cool evolved stars still is uncertain. The perceptive reader will discover a number of provocative research directions embedded in the many fine contributions herein.

ISBN:
Category : Science
Languages : en
Pages : 240
Book Description
"These proceedings are an overview of the status of the Hinode mission a year after launch with particular emphasis on instrument performance and the scientific results from the first data release. Hinode was designed to study the sun at high spatial and temporal resolution in order to answer the fundamental questions on how its magnetic fields are formed and evolve, and how their interaction with the solar plasma creates the wide variety of active phenomena that are observed on the sun. The papers presented at the conference and published in this volume contain a number of new and significant advances in this area. The conference covered a broad range of topics that included the most pressing open questions in solar physics, such as the emergence and evolution of magnetic fields, their impact on structuring and heating the solar atmosphere, the origins of the solar wind, and explosive energy release on all scales. This book therefor provides a broad picture of the current advances in observational solar physics made by Hinode, raising a number of new questions in several areas. It is suitable for researchers and graduate students interested in solar and stellar physics and in the processes involved in magnetized plasma environments in general."--Publisher's website

ISBN:
Category : Science
Languages : en
Pages : 226
Book Description
A symposium to celebrate the life of Bohdan Paczynski (1940-2007), Lyman Spitzer Jr. Professor of Theoretical Astrophysics at Princeton University, took place on 29-30 September 2007. Bohdan Paczynski impacted astronomy and astronomers alike with his innovative ideas, philosophies, and insight to astronomy, science and life in general. This volume has assembled thoughts, memories and scientific accomplishments influenced in one way or another by Bohdan, who was a Giant in his field. Nine friends, colleagues and admirers who have been touched by Paczynski personally, professionally, or both, contributed invited presentations. Topics in this volume include the influence of Bohdan Paczynski in the field of stellar evolution and variable stars, his crucial role in making the Optical Gravitational Lensing Experiment (OGLE) and the All Sky Automated Survey (ASAS) possible, and his revolutionary insistence on allowing anyone and everyone access to his stellar evolution code: The Paczynski Code. Also included are Bohdan's contributions to gravitational microlensing and the search for dark matter in the form of MACHOs. Particular emphasis is given to advances and unexpected discoveries from surveys such as MACHO, OGLE, and EROS. The impact Paczynski had on our understanding of gamma-ray bursts is also discussed. Finally, this celebration of Professor Bohdan Paczynski is completed with the addition of personal accounts of his life, brilliance, sense of humor, and inspiration to others. Paczynski's scientific contributions reach across all of astrophysics and bridge the gap between observation and theory. This book is of interest not only to those who knew him, but also to those who know of him and the immeasurable ways he left his mark on the community.

Category : Photography
Languages : en
Pages : 572
Book Description
"These proceedings of the first meeting of the Subaru International Conference Series held in December 2007 in Hayama, Japan, provide unique up-to-date overviews of the history of galaxy formation and the evolution of the universe. Fascinating and comprehensive observational results as well as many important theoretical achievements were presented by more than 150 active researchers from more than 15 countries and regions. The conference started off with results from recent cutting-edge observations of the very high-redshift universe extending into the cosmic reionization era, together with some theoretical interpretations and predictions for the first generation of galaxies. The history of mass distributions and structure formation at later cosmic times, including clusters of galaxies, was discussed extensively in presentations based on various panoramic survey data sets. Our aim was to showcase and understand the intrinsic galaxy-formation bias in the high-redshift universe and also the role of external environmental effects during the hierarchical assembly of galaxies into denser regions. Various populations of distant galaxies at different redshifts, discovered and studies by many different techniques, were introduced along with the physical relationship between these populations. Our discussion were aimed at assembling these pieces of jigsaw puzzles together into a panoramic and yet detailed structures of the Milky Way Galaxy and the Local Group galaxies were also presented and discussed as a complementary approach to the studies of the high-redshift Universe. In total, 19 invited talks, 46 contributed talks, and 87 poster papers combined to build up a picture of the history of galaxies over the cosmic age. This book is suitable for researchers who are interested in both observational and theoretical aspects of galaxy formation and cosmology, and especially for students seeking an overview of knowledge about galaxy formation to date."--Publisher's website

Mass Loss from Stars and the Evolution of Stellar Clusters
Author: Alex de Koter
Publisher:
ISBN:
Category : Mass loss (Astrophysics)
Languages : en
Pages : 512
Book Description
"In the spring of 2006 a four day international workshop was held in Lunteren, The Netherlands, in honor of the formal retirement of Prof. Henny Lamers. These proceedings provide a comprehensive overview of mass loss in massive stars and of the dynamical fate of clusters. The dynamical evolution of clusters is affected by stellar winds, mass loss outbursts and supernova explosions as well as by the loss of stars in dynamical interactions, thus linking the two central themes of the workshop. It is becoming clear that mass loss by radiation pressure on spectral lines is not only at work in normal O, B, and A stars but also in Luminous Blue Variables and Wolf-Rayet stars. The importance of these line-driven winds relative to outbursts in the Luminous Blue Variable phase of evolution is under debate. A central issue in this discussion is the importance of small and possibly large scale structure in stellar winds and its implications for the measured mass loss rates. These proceedings report on progress establishing wind properties, on theoretical predictions of mass loss and wind structure as a function of stellar properties, and on the effects of mass loss on the evolution of massive stars. As a result of dynamical interactions, clusters may dissolve completely over time. Observational studies of cluster dissolution timescales as a function of cluster formation history and cluster and environmental properties, are at the focus of cluster studies in the last decade. A key topic discussed in this book is whether the old globular clusters we observe today were once similar to present-day massive young clusters. The mass function of the two types of clusters is observed to be different. Is this a result of dynamical evoltuion or were the mass functions different at formation? The 12 invited reviews, 18 contributed talks, 48 poster papers, and two discussion sessions combine to provide and in-depth assessment of both observational and theoretical issues. The book is suitable for researchers and graduate students interested in stellar astrophysics and cluster dynamics."--Provided by publisher.
