... Right: Schematic of disk reprocessing in X-ray pulsars. The hard (power-law spectrum) X-ray beam sweeps around and illuminates the accretion disk, which reradiates a soft X-ray (blackbody) component. ... X-ray binaries owe their prominence to one of the most efficient energy release mechanisms known: accretion onto a compact object. In the accretion process gas from the atmosphere of the less dense companion is accelerated toward the extremely dense compact star. ...

GRANAT is the Russian x-ray sattelite launched to the high apogee orbit (200,000 km) and operated almost for 10 years (1989 -1999) , carrying out four major instruments: French SIGMA coded-mask hard x-ray telescope (30-1000 keV), Soviet ART-P coded-mask telescope (2??-60?? keV), all-sky monitor WATCH (6-150 keV), and a gamma-burst detector PHEBUS . ...
