Binary systems and stellar mergers in massive star formation
@article{Bonnell2005BinarySA, title={Binary systems and stellar mergers in massive star formation}, author={Ian A. Bonnell and Matthew R. Bate}, journal={Monthly Notices of the Royal Astronomical Society}, year={2005}, volume={362}, pages={915-920} }
We present a model for the formation of high-mass close binary systems in the context of forming massive stars through gas accretion in the centres of stellar clusters. A low-mass wide binary evolves under mass accretion towards a high-mass close binary, attaining system masses of the order of 30-50 M ○. at separations of the order of 1 au. The resulting high frequency of binary systems with two massive components is in agreement with observations. These systems are typically highly eccentric…
