The Atmospheres of Early-Type Stars: Proceedings of a Workshop Organized Jointly by the UK SERCs Collaborative Computational Project No. 7 and the In [Paperback]
Notes: Brand New Item. Not shipped to AK, HI, APO, FPO, AE.
These workshop proceedings aim to provide a broad overview of recent developments in the study of hot stars, both from the observational and the theoretical point of view. Included are first results from the Hubble Space Telescope and ROSAT, the effects of non-radial pulsations, mass loss, magnetic fields, and diffusion, as well as modern theoretical methods to treat radiative transfer and compute model atmospheres. Many new results are described, including the discovery of a B star in the halo of M31. Together the reviews provide a general overview of hot-star spectroscopy suitable for preparing advanced lecture courses and as an introductory text for graduate students.Galactic B-type Stars.- Non-LTE analyses of B stars.- Galactic B-type supergiants.- On the determination of effective temperature and surface gravity using Str?mgren uvby? photometry.- The mass and helium discrepancy in massive young stars.- A comparison between the orbital masses of early type binary components and masses predicted by stellar evolution.- B-type stars in young clusters.- Chemical abundances in early B-type stars.- The determination of accurate cosmic abundances from B-type stellar spectra.- The origin of distant B-type stars in the galactic halo.- Galactic abundance gradients from ob-type stars in young clusters and associations.- Ionizing radiation from early-type stars.- Abundance patterns in a stars: Carbon and silicon.- Quantitative analysis of A-type supergiants.- Abundances in rapidly rotating a stars.- Statistical equilibrium of Al I/II in a stars and the abundance of aluminium in Vega.- Analyses of B-type stars in the Magellanic Clouds.- The chemical composition of main sequence stars in the Magellanic Clouds.- GHRS observations of O Stars in other galaxies.- The winds of hot stars in M31 and M33.- Wolf-Rayet stars.- Spectrophotometry of Wolf-Rayet stars.- Near-Infrared Spectroscopy of Galactic Wolf-Rayet Stars.- Luminous Blue Variables.- Observed evolutionary changes in the l3×
