It is straightforward to calculate the mass of a neutron star in a binary system, depicted in this artist’s concept (the neutron star is on the right, pulling material off its companion star at ...

Measuring stellar masses Astronomers can measure orbital size and period of a binary system easily enough from observations, so with those two pieces they can calculate the total mass of the system.

The distances between stars in binary systems and their orbital periods differ considerably from binary to binary, and a system can be defined by these orbital distances.

Astronomers have observed primordial material that may be giving birth to three planetary systems around a binary star in unprecedented detail.

Data from NASA’s Chandra X-ray Observatory has revealed faint remnants of a supernova explosion and helped researchers determine that Circinus X-1 — an X-ray binary — is the youngest of this ...

One example of this is when there is a binary star system that is orbited by a large planet that travels along a polar path of the two stars. So, instead of revolving in the same direction as the ...

Last month astronomers announced the first discovery of multiple planets orbiting a pair of stars. Binary star systems, which comprise two stars orbiting around a common point, are very common ...
