Nucleosynthesis in Massive Stars
Space Science Reviews, 1993We 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.

The evolution of massive stars to explosion
Space Science Reviews, 1994We review the possible evolutionary paths from massive stars to explosive endpoints as various types of supernovae associated with Population I and hence with massive stars: Type II-P, Type II-L, Type Ib, Type Ic, and the hybrid events SN 1987K and SN 1993J.

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.

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

How Massive Single Stars End Their Life
, 2002How massive stars die—what sort of explosion and remnant each produces—depends chiefly on the masses of their helium cores and hydrogen envelopes at death.

Self-similar fragmentation regulated by magnetic fields in a region forming massive stars
Nature, 2015Most molecular clouds are filamentary or elongated. For those forming low-mass stars (8 solar masses). But whether the core field morphologies are inherited from the intercloud medium or governed by cloud turbulence is unknown, as is the effect of ...

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

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.

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.
