This book was released on 1991-07-31 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of stellar atmospheres is one of the most important branches of modern astrophysics. It is first of all a major tool for understanding all aspects of stars. As the physical properties of their outer layers can now be found with high precision, firm conclusions can be drawn about the internal structure and evolution of stars. Moreover, improvements in our knowledge of the chemical composition of stars is shedding new light on the chemical evolution of galaxies and of the Universe as a whole. Because the outer layers of stars are among the best-understood astrophysical objects, the theory of stellar atmospheres plays an important role in the study of many other types of objects. These include planetary nebulae, H II regions, interstellar matter, and objects of interest in high-energy astrophysics, such as accretion disks (close binaries, dwarf novae, cataclysmic variables, quasars, active galactic nuclei), pulsar magnetospheres, and Seyfert galaxies. Finally, as stars provide a laboratory in which plasmas can be studied under more extreme conditions than on earth, the study of stellar atmospheres has strong connections with modern physics. Astronomical observations provided a vital stimulus in the early stages of quantum theory and atomic physics; even today topics such as low-temperature dielectronic recombination develop hand in hand with the interpretation of stellar and nebular spectra. Early work on MHD was similiarly motivated. Many such connections remain to be explored.

Download or read book The Opacity Project written by Opacity Project Team and published by CRC Press. This book was released on 1994-01-01 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Opacity is a quantity that determines the transport of radiation through matter and is important in many problems in physics and astrophysics. To calculate opacities, one requires atomic data for a large number of processes involving the absorption and scattering of radiation. Stellar opacities are of particular interest in astrophysics because of their importance for theories of stellar structure and stellar pulsations. Taking advantage of advances in computational atomic and plasma physics and of the availability of powerful supercomputers, The Opacity Project, Volume 2: Selected Research Papers-Atomic Data Tables for S to Fe presents accurate atomic data required for opacity calculations. The work includes computation of energy levels, oscillator strengths, photoionization cross sections, and parameters for pressure broadening of spectral lines. The book uses several different methods of computation to calculate the same data, thereby providing a check on the validity of the data. Divided into two parts, the first presents seven key research papers that review available data and detail the relevant atomic data calculations while the second part provides tables of energy levels and oscillator strengths for the elements S, Ar, Ca and Fe. The Opacity Project Team is comprised of 30 experts from 13 leading international laboratories and observatories in atomic physics and astrophysics.

This book was released on 2012-12-06 with total page 937 pages. Available in PDF, EPUB and Kindle. Book excerpt: The XXth General Assembly of the International Astronomical Union was held in Baltimore, Maryland USA from August 02 to 11, 1988. The Inaugural Ceremony on August 02 was held in the presence of representatives of the United States Governn:ent, t~e S~ate of Maryland, the City of Baltimore and the host institution -the Johns Hopkins Umverslty- as well as of the National and Local Organising Committees. The scientific programme maintained the high standards of the Union and the scientific proceedings may be found either in this volume or in volume 8 of Highlights of Astronomy. The scientific programme was organised by the 40 Commission Presidents and coordinated by the General Secretary (1985-1988), Dr. J.-P. Swings. The local arrangements were effectively made through the National Organising Committee under the Chairmanship of Prof. F. Drake and the Local Organising Committee under the co-Chairmanship of Prof. A. Oavidsen and Dr. R. Giacconi. The smooth day to day operation of the meeting resulted from the incomparable dedication of Karen Weinstock and Harold Screen.
