Massive Star Evolution [PDF]

open access: yesSymposium - International Astronomical Union, 1999
The evolution of massive stars is far from being fully understood, as we outline by pointing to a number of open problems related to massive stars in the Magellanic Clouds. We argue that rotation may be a key ingredient in the physics of massive stars.

The evolution of massive binary systems [PDF]

open access: yesSerbian Astronomical Journal, 2020
The evolution of massive stars in close binary systems is significantly different from single star evolution due to a series of interactions between the two stellar components.

Eta Carinae: The Dissipating Occulter Is an Extended Structure

open access: yesThe 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 ...

Yellow Supergiants and Post-red Supergiant Evolution in the Large Magellanic Cloud

open access: yesThe 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.

Profiling young massive stars [PDF]

open access: yesProceedings of the International Astronomical Union, 2007
AbstractWe present the results of spectral energy distribution analysis for 162 of the 405 sources reported in the SIMBA survey of Hill et al. (2005). The fits reveal source specific parameters including: the luminosity, mass, temperature, H2 number density, the surface density and the luminosity-to-mass ratio.

Multiplicity of Massive Stars [PDF]

open access: yesSymposium - International Astronomical Union, 2001
We discuss the observed multiplicity of massive stars and implications on theories of massive star formation. After a short summary of the literature on massive star multiplicity, we focus on the O-and B-type stars in the Orion Nebula Cluster, which constitute a homogenous sample of very young massive stars.

Massive Hypervelocity Runaway Stars in the Large Magellanic Cloud

open access: yesThe 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.

Nucleonic Direct Urca Processes and Cooling of the Massive Neutron Star by Antikaon Condensations

open access: yesAdvances 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.

Early-forming Massive Stars Suppress Star Formation and Hierarchical Cluster Assembly

open access: yesThe 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
