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 ...

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

Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or “hot Jupiters,” astronomers can spend months or years ...

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

Astronomers report the discovery of a new binary system, designated LAMOST J065816.72+094343.1. The newfound binary consists ...

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 -- ...

Astronomers have captured a rare and remarkably close view of a giant planet circling a pair of tightly bound suns, offering one of the clearest real-world echoes yet of the fictional world Tatooine.

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 ...
