Nucleosynthesis in Massive Stars

Space Science Reviews, 1993
We discuss three aspects of the nucleosynthesis in massive and intermediate—mass stars during their early evolutionary phases. These are related to the CNO abundances in giant or supergiant stars, to the 26A1 yield from massive stars via stellar wind, and to the production of the s—process nuclei in massive stars.

Massive Stars

2009
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

Wind asymmetries in massive stars

Space Science Reviews, 1994
We 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

Evolution of massive stars

1989
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 Star Evolution

2004
Supernovae are of wide interest to the astronomical community because they play a key role in the nucleosynthetic evolution of galaxies, stellar remnant populations, the energetics and phase balance of the interstellar medium (ISM), the interpretations of observations of distant galaxies, models of galaxy formation and evolution, the physics of star ...
