| Abstract: |
Common Envelope (CE) phases serve a critical role in the creation of high
mass X-Ray binaries (HMXBs) as the primary force which moves initially
loosely bound binary companions into tight orbits capable of supporting
efficient material transport onto the compact object. We investigate the
impact of CE phases on young (< 20 Myr) and bright
(Lx< 1 × 1036 erg s-1) X-ray binaries, finding CE evolution to
produce a robust population of HMXBs with luminosities powered by Roche lobe
overflow onto black hole accretors. We find that HMXBs formed through CE
evolution match the observed luminosity and spatial distribution and
metallicity dependence of the peculiar high luminosity extension of HMXBs
known as the ultra-luminous X-ray sources (ULX). |
