An international research team announces the discovery of a new exoplanet orbiting a binary star system. Named HD 143811 b, ...

Astronomers struggle to understand how planets form in binary star systems. Early models suggested that the gravitational tug-of-war between two stellar bodies would send young planets into eccentric ...

We examine characteristics of circumbinary orbits in the context of current planet formation scenarios. Analytical perturbation theory predicts the existence of nested circumbinary orbits that are ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” 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 ...

Binary stars as a research area encompass the observational, theoretical, and computational study of gravitationally bound stellar pairs, focusing on their formation, orbital dynamics, mass transfer, ...

Astronomers have confirmed that differences in binary stars' composition can originate from chemical variations in the cloud of stellar material from which they formed. The results help explain why ...
