Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such systems ...

Astronomers have developed the most realistic model to date of planet formation in binary star systems. The researchers, from the University of Cambridge and the Max Planck Institute for ...

In X-Ray binary systems, a compact object (like a Black Hole, a Neutron Star or a White Dwarf) usually rotates about an optical star. An X-Ray binary with a Neutron Star as the compact object can be ...

Rare star system This is the first time that a short-life binary consisting of a neutron star and a helium star has been detected. (Courtesy: Bureau of International Cooperation, Chinese Academy of ...

In theory, it could happen – one of the very first solutions to the three-body problem was this scenario. But it is very unlikely to be stable over time. You need the stars to have near equal mass and ...
