Sb. Popov et Me. Prokhorov, SPATIAL-DISTRIBUTION OF THE ACCRETION LUMINOSITY OF ISOLATED NEUTRON-STARS AND BLACK-HOLES IN THE GALAXY, Astronomy and astrophysics, 331(2), 1998, pp. 535-540
We present here a computer model of the spatial distribution of the lu
minosity, produced by old isolated neutron stars and black holes accre
ting from the interstellar medium. We show that the luminosity distrib
utions in the Galaxy have a ring structure, with a maximum at approxim
ate to 5kpc radius.
