Next: The Evolutionary Status of Up: No Title Previous: Massive X-ray Binaries . After 25 years of pulsar studies, a radiopulsar has been discovered in a binary system with a massive optical companion (Johnston et al. ... As shown in the very first calculations of joint evolution of NS and normal stars in binaries (Kornilov and Lipunov, 1983b[ 86 ]) a considerable fraction (maybe, the majority) of NS in binary systems having an optical companion must be at the ejector љ (E) state. ...

Weiss ( CXC ), NASA Explanation: Binary star system GRO J1655-40 consists of a relatively normal star about twice as massive as the Sun co-orbiting with a black hole of about seven solar masses . ...

... 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. ...

... Recent studies indicate that stars are most likely forming within the binary and multiple systems. ... During several years we are conducting the observations of such multiple stellar systems at the BTA telescope in order to find their companions and study the properties therein. ... This star is interesting in that it may be a dynamically unstable multiple star, meaning that over time, such systems will split into individual stars. ... A bright component is a very tight spectroscopic binary star. ...
