Next: The Model Up: No Title Previous: Radiopulsars as Sources of . In this section, we study the evolution of stellar populations on a time-scale of 10 Myr for a starburst љ occurring under conditions similar to those in the Galactic Center (see Lipunov et al. (1995d)[ 126 ]). We estimate the expected number of X-ray transient љ sources (NS + MS star), super accreting BH, and BH + supergiant binaries, all as functions of time elapsed after the burst. ...

... December 30, 1995 . LMC X-1: A Black Hole Candidate . ... Explanation: The strongest source of X-rays in the Large Magellanic Cloud originates from an unusually energetic binary star system . This strong source, dubbed LMC X-1, is thought to be a normal and compact star orbiting each other. ... Motion in the binary system indicates the compact star is probably a black hole , since its high mass - roughly five times that of our Sun - should be enough to cause even a neutron star to implode. ...
