No, that&#x27;s wrong. Narayan, R. and McClintock, J.E., New Astronomy Reviews, 51, 733–51, 2008 [arxiv: https://arxiv.org/abs/0803.0322 ] has a beautiful chart (Fig. 8) comparing the quiescent bolometric luminosity of star-to-accreting-neutron star binaries and star-to-accreting-black hole binaries. Observed NS binaries are brighter than observed BH (candidate) binaries. This is one test for whether a compact accretor in a binary is a BH rather than an NS. This technique was used by Bennett…</p><p><a href="https://hackerpaper.kaipfister.de/p/0803.0322/">Paper and discussion history</a>. A mention is not an endorsement.</p>astro-ph
