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 ...

More than 70% of massive stars are born in close binary systems, where gravitational tugs and mass transfer between companions dramatically alter their evolution. Yet once the interaction ends—whether ...

A pair of stars with three planets in orbit around one star or the other is the first system of its kind that has been confirmed. Pairs of stars, known as binaries, appear to be more common in the ...

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, ...

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 ...

Visualization of gas flows around a binary protostar system calculated by ATERUI III. The gas shown in red orbits around one of the two protostars. The gas shown in blue orbits around the combined ...

Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or “hot Jupiters,” astronomers can spend months or years ...

An international team of researchers has detected a binary star orbiting close to Sagittarius A*, the supermassive black hole at the centre of our galaxy. It is the first time a stellar pair has been ...

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 ...
