Astronomers have made a groundbreaking discovery of three Earth-sized planets orbiting within a compact binary star system. This rare configuration, where planets circle two stars simultaneously, ...

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 ...

University of Copenhagen astrophysicists help explain a mysterious phenomenon, whereby stars suddenly vanish from the night sky. Their study of an unusual binary star system has resulted in convincing ...

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 ...

A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

Astronomers from the California Institute of Technology (Caltech) and elsewhere report the discovery of a binary system consisting of two brown dwarfs undergoing stable mass transfer. The detection 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 ...

A team of astronomers from The Graduate University for Advanced Studies, the National Astronomical Observatory of Japan, and other universities have captured the first direct image of a young binary ...

Stars are the fundamental building blocks of our universe. Most stars host planets, like our Sun hosts our solar system, and if you look more broadly, groups of stars make up huge structures such as ...
