The multiplicity of massive stars [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractBinaries are excellent astrophysical laboratories that provide us with direct measurements of fundamental stellar parameters. Compared to single isolated stars, multiplicity induces new processes, offering the opportunity to confront our understanding of a broad range of physics under the extreme conditions found in, and close to, astrophysical

Eta Carinae: The Dissipating Occulter Is an Extended Structure
The Astrophysical Journal, 2023 Previous Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph (STIS) longslit observations of Eta Carinae ( η Car) identified numerous absorption features in both the stellar spectrum, and in the adjacent nebular spectra, along our line of ...

Presupernova Evolution and Explosive Nucleosynthesis of Rotating Massive Stars in the Metallicity Range −3 ≤ [Fe/H] ≤ 0 [PDF]
Astrophysical Journal Supplement Series, 2018 We present a new grid of presupernova models of massive stars extending in mass between 13 and 120 , covering four metallicities (i.e., [Fe/H] = 0, −1, −2, and −3) and three initial rotation velocities (i.e., 0, 150, and 300 km s−1).

Yellow Supergiants and Post-red Supergiant Evolution in the Large Magellanic Cloud
The Astronomical Journal, 2023 The empirical evidence for an upper-mass limit for the red supergiant (RSG) progenitors of the Type II-P SNe at about 18 MSun, raises questions about the fate of the most luminous, most massive RSGs.

On the formation of massive stars [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We present a model for the formation of massive ($M > 10 M_\odot$) stars through accretion-induced collisions in the cores of embedded dense stellar clusters. This model circumvents the problem of accreting onto a star whose luminosity is sufficient to reverse the infall of gas.

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.

Evidence for quark-matter cores in massive neutron stars [PDF]
Nature Physics, 2019 The theory governing the strong nuclear force—quantum chromodynamics—predicts that at sufficiently high energy densities, hadronic nuclear matter undergoes a deconfinement transition to a new phase of quarks and gluons1.

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

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 ...
