Common Envelope Evolution

The diverse physical processes that occur in post-main-sequence binaries contain many open questions.  Stellar, sub-stellar, or compact-object companions orbiting within ~10 AU of their host stars may strongly interact as the primary star evolves off the main sequence and the orbits destabilize.  Such systems likely incur a common envelope phase, an important but brief channel in stellar evolution, that results in either the emergence of a short-period binary or the destruction of the companion (or the primary’s core).  In this talk, I will highlight recent numerical and theoretical work on common envelopes.
