On the origin of the metallicity dependence in dynamically formed extragalactic low-mass X-ray binaries
N. Ivanova, T. Fragos, D. -W. Kim +6
Globular clusters (GCs) effectively produce dynamically-formed low-mass X-ray binaries (LMXBs). Observers detect ~100 times more LMXBs per stellar mass in GCs compared to stars in…
