In the last few years a very similar phenomenon has been observed in some X-ray binaries, binary stellar systems with one gravitationally-compact object (black hole or neutron star) and an "normal" star part of whos atmosphere is captured by the compact object. ... The compact objects (a few solar masses) are much smaller than those inferred in AGN (10 9 solar masses), and the sizes much smaller, so the analogy may not be complete. ...
