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 ...

The Hubble Space Telescope has captured imagery of the R Aquarii binary star system from 2014-2023. The images have been time-lapsed here to show the evolution of the region. Credit: NASA, ESA, M.

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 ...

Astronomers have discovered humanity's first known example of a rare binary system doomed to end in a massive kilonova explosion. This type of cosmic phenomenon is so rare that scientists estimate ...

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 ...

Washington DC — New theoretical work shows that gas-giant planet formation can occur around binary stars in much the same way that it occurs around single stars like the Sun. The work is presented ...
