How many Earth-sized exoplanets orbit binary star systems (two-star systems)? This is what a recent study accepted by Astronomy & Astrophysics hopes to address as an international team of researchers ...

In the subsequent analysis, we will refer to the primary as D9a, whereas the secondary companion will be denoted as D9b. With the binary orbiting Sgr A*, this three-body system is divided into an ...

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 ...

For the first time, astronomers have spotted a rapidly spinning neutron star that is gravitationally bound to a helium star companion. The discovery of this unusual binary system helps confirm a long ...

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 ...

An international team of astronomers reports the discovery of a new pre-main-sequence eclipsing binary system. The newfound binary, designated MML 48, consists of two young low-mass stars. The finding ...
