Talk Title:  “High-energy Physics, Nuclear Physics and Climate Change in the Companions of Millisecond Pulsars (!).”

Abstract:

It has for decades been understood that low mass X-ray binaries evolve into millisecond pulsars.  However we have recently understood that for several reasons, this transition is not one-way, and happens more than once.  I will discuss the subtle physical effects in the companion stars which lead to this complexity, notably pulsar-induced air showers and spallation, thermally driven winds, bloating, and limit cycles in accretion. Properties of observed companion stars of millisecond pulsars confirm and motivate this rich theoretical understanding.
