The physics behind stable circular orbits in binary stars explores how gravitational forces balance to create long-term orbital stability between two stars. Learn the fundamental principles of ...

Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of ...

The eccentricity in the orbits of these black holes, detected using gravitational waves, could tell the story of their creation. When you purchase through links on our site, we may earn an affiliate ...

Astronomers may have identified a rare binary star system where one star orbits within the volume of its companion. This discovery opens a new window into the evolution of double star systems. The ...

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 ...

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 ...

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 ...

New research shows how disruptions to binary star systems could be the key to detecting space's most confounding substance — dark matter. When you purchase through links on our site, we may earn an ...

In 2018, astronomers discovered a pair of brown dwarf stars orbiting each other in a rare system known as an eclipsing binary. Further observations show that the binary, named 2M1510, is even more ...

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 ...
