Astronomers have investigated a puzzling binary star system in which two stars that may have formed together now show ...

A triple star system in which the stars all eclipse one another from our vantage point is standing out as one of the best ...

New simulations show that interactions with a magnetic field can work to decrease the distance between still forming binary ...

Scientists have uncovered a surprising force that may help explain how binary star systems form so quickly. New supercomputer ...

Astronomers believe they may have found evidence that one star in a faraway binary ...

Radio astronomers have decoded a peculiar repeating radio signal from deep space, tracing it to a vampiric binary star system ...

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 ...

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 ...

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 ...
