The Evolution of Massive Stars [PDF]
Symposium - International Astronomical Union, 1997 Massive stars are the crossroads of many important astrophysical problems and thus a proper understanding of their evolution is very needed. They are the main sources of UV radiation, by heating the interstellar dust they produce the far-IR luminosities of galaxies.

Developments in Physics of Massive Stars [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractNew constraints on stellar models are provided by large surveys of massive stars, interferometric observations and asteroseismology. After a review of the main results so far obtained, we present new results from rotating models and discuss comparisons with observed features. We conclude that rotation is a key feature of massive star physics.

Massive Stars in the Galactic Center [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractWe present results of two studies aiming at better understanding the properties of massive stars in the Galactic Center. We focus on the youngest and oldest of the three massive clusters harboring this region, namely the Arches and central cluster.

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.

Zooming in to Massive Star Birth [PDF]
The Astrophysical Journal, 2018 Abstract We present high-resolution (0.″2, 1000 au) 1.3 mm ALMA observations of the massive infrared dark cloud clump, G028.37+00.07-C1, thought to harbor the early stages of massive star formation. Using (3–2), we resolve the previously identified C1-S core, separating the

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

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.

Monotonicity of the Cores of Massive Stars
The Astrophysical Journal, 2023 Abstract Massive stars are linked to diverse astronomical processes and objects including star formation, supernovae and their remnants, cosmic rays, interstellar media, and galaxy evolution. Understanding their properties is of primary importance for modern astronomy, and finding simple rules that characterize them is especially useful.
