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.

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.

Young Massive Star Clusters [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2010
Young massive clusters (YMCs) are dense aggregates of young stars that form the fundamental building blocks of galaxies. Several examples exist in the Milky Way Galaxy and the Local Group, but they are particularly abundant in starburst and interacting galaxies.

Massive star and star cluster formation [PDF]

open access: yesProceedings 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.

Very massive runaway stars from three-body encounters [PDF]

open access: yes, 2010
Very massive stars preferentially reside in the cores of their parent clusters and form binary or multiple systems. We study the role of tight very massive binaries in the origin of the field population of very massive stars.

RCW36: characterizing the outcome of massive star formation [PDF]

open access: yes, 2013
Massive stars play a dominant role in the process of clustered star formation, with their feedback into the molecular cloud through ionizing radiation, stellar winds and outflows.

The Complex Upper HR Diagram

open access: yesGalaxies, 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.
