General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

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 ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

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 ...

An international team of researchers has just revealed the existence of three Earth-sized planets in the binary stellar system TOI-2267 located about 190 light-years away. This discovery, published in ...

The Kuiper Belt object Altjira was thought to be a binary, but closer analysis suggests that it is highly likely to be a triple system This raises the question of the three-body problem; if Altjira ...

The mystery of how planets and icy objects formed in the farthest reaches of our solar system just took an exciting turn. A team of researchers from NASA recently uncovered strong evidence for a rare ...
