Only a few dozen of these short-lived binaries exist in the galaxy at a time, making the serendipitous find extremely ...

When white dwarfs—the hot remnants of stars like our sun—are orbited closely by another star, they sometimes steal mass away ...

When white dwarfs-the hot remnants of stars like our Sun-are orbited closely by another star, they sometimes steal mass away from their companion. The ...

The common envelope phase is a not-well-understood step in the complex chain of events in binary stars’ lifetimes. By generating artificial populations of stars in their model, Breivik said they can ...

Certain antihistamines found in common allergy medications and sleep aids are liked to an increased dementia risk. Doctors share what you should take instead.

Binary star systems are pairs of stars held together by gravity, orbiting a common center of mass. More than half of all stars in our galaxy are part of a binary or multiple-star system making them ...

Astronomers may have discovered a rare type of binary star system, where one star used to orbit inside its partner.

The discovery of this unusual binary system helps confirm a long theorized—but rarely seen—cosmic process called common envelope evolution.

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 ...

The formation of such exotic binary systems is not fully understood, because it can involve a variety of complex processes. Theory predicts that binary systems can experience a common envelope phase, ...
