On the nature of X-ray sources in early-type galaxies.

JUETT A.M.

Abstract (from CDS):

We show that the observed relationship between the fraction of low-mass X-ray binaries (LMXBs) found in globular clusters (GCs) and the GC-specific frequency for early-type galaxies is consistent with an LMXB formation model in which the field population of LMXBs is formed in situ via primordial binary formation. The suggestion that a significant fraction of the field LMXB population in early-type galaxies was formed in GCs is not required by the data. Finally, we discuss observational studies that will test this model more thoroughly.
