Wind asymmetries in massive stars
Space Science Reviews, 1994We are in the process of surveying the linear polarization in luminous, early-type stars. We here report on new observations of the B [e] stars S 18 and R 50, and of the Luminous Blue Variables HR Car, R 143, and HD 160529. Together with previously published data, these observations provide clear evidence for the presence of intrinsic polarization in 1

The term massive star is not very precise, and in the following we shall use it for stars with zero age main sequence (ZAMS) masses M ZAMS above approximately 15 M ⊙. Note, however, that these abjects may achieve actual masses well below 15 M ⊙ during their evolution, as a consequence of mass loss due to stellar winds, pulsations, or other processes. M

Massive Stars: Setting the Stage
Space Science Reviews, 1993The paper gives a summary of the situation mid-1993 of theory and observations regarding massive stars. I describe: stellar mass loss and its implications, pre-main-sequence evolution, the main sequence, problems of atmospheric instability, Luminous Blue Supergiants, Yellow Hyper-giants, Wolf—Rayet stars and supernovae.

This collection of papers from the Space Telescope Science Institute Symposium on massive stars addresses the many aspects of astrophysics in which these stars play an important role. Review papers are presented from both observational and theoretical work by world experts in the study of these rare stars. Topics discussed include star formation in the

Properties of massive star evolution
Space Science Reviews, 1994New models of massive stars have been calculated as a part of a project aimed at the construction of an extended grid of stellar tracks for several metallicities, covering all the main evolutionary phases of low, intermediate and massive stars, with updated physics.

Massive stars in the galactic center
New Astronomy Reviews, 2000We review quantitative spectroscopic studies of massive stars in the Galactic Center clusters. Thanks to the impressive evolution of IR detectors an the new generation of line blanketed models for the extended atmospheres of hot stars we are able to accurately derive the physical properties of the massive stars in these clusters.
