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

Based on those details, the researchers think they've discovered a new type of stellar system — a collection of gravitationally bound stars that's not quite a galaxy but not a known type of star ...

Another odd type of star is sub-subgiant, Gosnell says. These stars also are found in binary systems, and are transitioning from the main sequence to the red giant branch, though they stay dimmer.

An international team of scientists led by astronomers from the University of Wisconsin–Madison has produced the most ...

The trick is that you need a system with at least two stars. McInnes started by searching for any points within a binary star system that could host a stable Dyson sphere arrangement, where the ...

An international team of astronomers reports the discovery of a new ultracompact binary of the AM CVn type exhibiting ...

A planetary system is shaped at the boundary of order and chaos. It starts out as a molecular cloud—a big, cold clump of mostly hydrogen gas that can collapse to make stars. As central stars ...

This type of star system may not limit the evolution of life, however, if the conditions are right. Research presented at the American Astronomical Society meeting in January this year revealed ...

For the first time, a team of astronomers have observed a binary star system that is destined to end in a type 1a supernova in this new study. The stars’ close proximity to us is an added bonus.
