New Hubble observations explain how blue straggler stars form, showing that binary systems in low-density clusters play a key role ...

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 ...

"Our study provides a new direction to understand the whole evolutionary history of massive stars toward the formation of ...

How many Earth-sized exoplanets orbit binary star systems (two-star systems)? This is what a recent study accepted by Astronomy & Astrophysics hopes to address as an international team of researchers ...

In a breakthrough for exoplanet science, astronomers have discovered three Earth-sized planets orbiting both stars in a compact binary system located around 190 light-years away. The system, known as ...

N-body simulations of primordial binaries and tidal capture in open clusters / Sverre J. Aarseth -- When and how can binary data test stellar models / Birgitta Nordstrom / Johannes Anderson -- ...

Citizen scientists have successfully located thousands of previously unknown pairs of “eclipsing binary” stars, NASA announced in June. The ongoing initiative helps space researchers hunt for ...
