White dwarf stars represent the evolutionary endpoints of medium- and low-mass stars, comprising the dense, electron-degenerate cores left after nuclear fuel exhaustion. In binary systems, ...

Interacting binary stars, a class of stellar systems consisting of two gravitationally bound stars, exhibit a rich diversity of phenomena driven by mass transfer and angular momentum exchange. In many ...

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 discovered a population of massive stars that have been stripped of their hydrogen envelopes by their companions in binary systems. The findings shed light on the hot helium stars ...

have been combined into a movie. In merely 3 days, the stars swing around each other. As seen from the earth, they pass in front of each other twice during a full revolution, producing eclipses during ...

At the centre of the Milky Way is a supermassive black hole called Sagittarius A*. It is roughly 27,000 light years from Earth and 23.5 million kilometres in diameter. In a world first, a team of ...

A team of astronomers have used the United Kingdom Infrared Telescope (UKIRT) on Hawaii to discover four pairs of stars that orbit each other in less than 4 hours. Until now it was thought that such ...
