| Abstract: |
Observations of massive
binaries offer us key insight about the formation,
evolution, and destinies of massive stars.
Here I review some advances in observational and
theoretical studies of massive binaries. Surveys for
binaries using radial velocity, photometric, and
high angular resolution methods show that
the binary frequency is high for O stars in clusters.
Evolutionary models for interacting
binaries demonstrate the importance
of angular momentum transfer during Roche lobe overflow.
The mass gainer may reach critical rotation and stem
further accretion, and there are many observed cases
that show the consequences of such mass loss
and transfer. New hydrodynamical models describe
colliding wind physics in eccentric
binaries such as η Carinae and WR 140.
All these research topics are championed
by Tony Moffat, and the current richness of this
field is due in large measure to his energetic
pursuits. |
