Master Thesis - Sterrenkunde RU Nijmegen
... Stars are usually born in groups from large clouds, which contract when gravity overcomes the internal pressure. The most important parameter of a star is its mass at birth, which determines the stars further evolution. Stars with a mass of 0.08M or more, fuse hydrogen to helium in their core. Star ...

The Massive Star Population of Cygnus OB2

Work over the past decade has assembled the data needed to form a much fuller view of the OB population in Cyg OB2, thanks to a combination of new spectroscopic surveys of both primary OB stars and their binary companions (e.g., Kiminki et al. 2007; Kobulnicky et al. 2012), improvements in the stell ...
