Early-forming Massive Stars Suppress Star Formation and Hierarchical Cluster Assembly
The Astrophysical Journal, 2023 Feedback from massive stars plays an important role in the formation of star clusters. Whether a very massive star is born early or late in the cluster formation timeline has profound implications for the star cluster formation and assembly processes. We

Nucleonic Direct Urca Processes and Cooling of the Massive Neutron Star by Antikaon Condensations
Advances in Astronomy, 2020 Nucleonic direct Urca processes and cooling of the massive neutron stars are studied by considering antikaon condensations. Calculations are performed in the relativistic mean field and isothermal interior approximations.

Massive Hypervelocity Runaway Stars in the Large Magellanic Cloud
The Astrophysical Journal, 2023 Since the hypervelocity stars were discovered in the Milky Way, various mechanisms have been proposed to explain these runaway stars. Up to now, however, the dominant ejected mechanism of hypervelocity stars is still unclear.

Massive Stars as the Radiant Queens of the Universe—The Case of ζ Puppis
Universe, 2022 Since the Cosmic Dawn, massive stars have been playing a crucial role as the chemical recycling engines of galaxies that enable the birth of new stars and planetary systems, not only through the strong winds that they exhibit during their relatively ...

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.

The Astrophysical Journal, 2023 Extinction toward the Galactic Center (GC) is extreme and limits observations of its stars to the infrared. In addition, the extinction varies on scales of arcseconds.

Galaxies, 2019 Several decades of observations of the most massive and most luminous stars have revealed a complex upper HR Diagram, shaped by mass loss, and inhabited by a variety of evolved stars exhibiting the consequences of their mass loss histories.

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.

Asteroseismology of High-Mass Stars: New Insights of Stellar Interiors With Space Telescopes
Frontiers in Astronomy and Space Sciences, 2020 Massive stars are important metal factories in the Universe. They have short and energetic lives, and many of them inevitably explode as a supernova and become a neutron star or black hole.
