Description
Common-envelope events are fate-defining episodes in the
lives of close binary
systems. During a common envelope event, two stars
temporarily orbit within a shared
envelope, and the episode ends with an exciting outburst,
leaving behind either a
significantly shrunk binary, or a single merged star. I will
review what is new about
what we know the common envelope physics: when does a common
envelope start, how does
it proceed, what marks its end, and what are the new
theoretical constraints for
double white dwarf and double black hole binaries formation.
