Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open ...

Astronomers have identified a tightly bound pair of stars that are spiraling toward a catastrophic merger, turning a distant stellar system into a natural laboratory for testing gravity at its most ...

A newly identified super-Earth orbiting a nearby star has rapidly climbed to the top of astronomers’ wish lists for worlds ...

A planet has been discovered lurking in the habitable zone of not one, but two, stars. This far-off planet, situated around 310 light-years from Earth, has been found to exist within the two-star ...

Northwestern astrophysicist Chih-Chun “Dino” Hsu discovered the fourth set of dwarf binary stars ever found, in 2022. The stars, named LP 413-53AB, are closer and older than previously recorded ...

Astronomers have detected a binary star system orbiting Sagittarius A*, the Milky Way's central supermassive black hole. Just on the outskirts of a supermassive black hole roughly 4 million times more ...

For many years, binary star research was as neglected as an old Tamagotchi. Not anymore. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Some 90s ...

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 ...

Contact binary stars are systems in which both stellar components share a common envelope, resulting in complex interactions and energy transfer. These systems exhibit characteristic light curves that ...

How can red dwarf stars, which are both smaller and cooler than our Sun, influence the habitability potential for exoplanets orbiting them? This is what a recent study published in the Monthly Notices ...

What can binary stars comprised of two different types of stars teach astronomers about stellar evolution? This is what a recent study published in The Astrophysical Journal hopes to address as a team ...
