Astronomers using the NASA/ESA Hubble Space Telescope, along with other telescopes on the ground and in space, have discovered a new type of exotic binary star In the system AR Scorpii a rapidly ...

Using NASA's Kepler space telescope, Chinese astronomers have observed a binary star system known as KIC 5623923. As a result, they found that the investigated system is a faint eclipsing binary ...

Researchers at the Center for Astrophysics | Harvard & Smithsonian have observed a new type of binary star that has long been theorized to exist. The discovery finally confirms how a rare type of star ...

Astrophysicists have discovered the tightest ultracool dwarf binary system ever observed. The two stars are so close that it takes them less than one Earth day to revolve around each other. In other ...

Romeo and Juliet were a pair of doomed, star-crossed lovers. Now, astronomers have detected a pair of doomed star-crossed stars. Like Shakespeare's famously unlucky couple, two white dwarfs spiraling ...

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 ...

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 ...

Oddly enough, binary stars born from the same parental cloud of collapsing gas and dust aren't always identical twins. It's possible they even possess different kinds of orbiting planets. But, why ...

In theory, a planet may be able to orbit a binary star system in a figure of eight, but it may not be particularly stable, ...
