Massive stars in transition [PDF]
EAS Publications Series, 2004 We discuss the various post-main sequence phases of massive stars, focusing on Wolf-Rayet stars, Luminous Blue Variables, plus connections with other early-type and late-type supergiants. End states for massive stars are also investigated, emphasising connections between Supernovae originating from core-collapse massive stars and Gamma Ray Bursts.

The Astrophysical Journal Supplement Series, 2023 In our Galaxy, star formation occurs in a variety of environments, with a large fraction of stars formed in clusters hosting massive stars. OB stars have an important feedback on the evolution of protoplanetary disks orbiting around nearby young stars ...

Understanding the Death of Massive Stars Using an Astrophysical Transients Observatory
Frontiers in Astronomy and Space Sciences, 2018 The death of massive stars, manifested as gamma-ray bursts and core-collapse supernovae, critically influence how the universe formed and evolves. Despite their fundamental importance, our understanding of these enigmatic objects is severely limited.

Nucleosynthesis of 60Fe in massive stars [PDF]
New Astronomy Reviews, 2006 We discuss at some extent the production of Fe60 in massive stars in the range between 11 and 120 Msun both in the hydrostatic and explosive stages. We also compare the Fe60/Al26 gamma-ray line flux ratio obtained according to the present calculations to the detected value reported by INTEGRAL/SPI.

A Catalog of New Slowly Pulsating B-type Stars
The Astrophysical Journal Supplement Series, 2023 This paper reports the discovery of new slowly pulsating B-type stars. Based on the photometric, spectral, and astrometric data of the TESS, LAMOST, and Gaia surveys, we have found 286 new slowly pulsating B-type (SPB) stars and 21 candidates.

Massive star and star cluster formation [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractI review the status of massive star formation theories: accretion from collapsing, massive, turbulent cores; competitive accretion; and stellar collisions. I conclude the observational and theoretical evidence favors the first of these models.

Observational Properties of 155 O- and B-type Massive Pulsating Stars
The Astrophysical Journal Supplement Series, 2023 O- and B-type (OB-type) pulsating stars are important objects for studying the structure and evolution of massive stars through asteroseismology. A large amount of data from various sky surveys provides an unprecedented opportunity to search for and ...

Massive stars in their death throes [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008 The study of the stars that explode as supernovae used to be a forensic study, working backwards from the remnants of the star. This changed in 1987 when the first progenitor star was identified in pre-explosion images. Currently, there are eight detected progenitors with another 21 non-detections, for which only a limit on the pre-explosion luminosity
