Аннотация:Individual probability-density distributions for the masses of compact objects in 20 X-ray
binary systems have been constructed. The mass distributions were modeled using Monte-Carlo simu-
lations. The closeness of the components in systems with massive optical stars was taken into account
using K corrections. The parameters of the resulting black-hole mass distributions were obtained using
nonparametric statistical methods. The presence of a statistically significant mass gap in the range 3−5M
is confirmed. The currently observed probability-density distributions of the compact-object masses are
stable against small amounts of data contamination.
