The X-ray binaries in M83: Will any of them form gravitational wave sources for LIGO-VIRGO-KAGRA?

I Kotko, K Belczynski - Astronomy & Astrophysics, 2024 - aanda.org
There are 214 X-ray point sources (LX> 10 35 erg s− 1) identified as X-ray binaries (XRBs)
in the nearby spiral galaxy M83. Since XRBs are powered by accretion onto a neutron star …
