X-ray bursters: their origin and evolution

;
The question of how the bursting galactic x-ray sources originated is approached by considering the formation of binary stars by tidal capture both in globular clusters and in the central bulge of the Galaxy. Roughly half of the bursters observed outside clusters could be former members of clusters that have decayed. The number of known bursters and their galactic distribution can be explained if bursters have an average lifetime tau> or approx. = (2--3) x 10/sup 9/ yr and if globular clusters were 10/sup 2/--10/sup 3/ times as numerous in the past.
