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 ...

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 ...

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 ...

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 ...

Astronomers have identified a rare and extraordinary triple star system in our galaxy using NASA’s Transiting Exoplanet ...

"This makes TOI-2267 the first binary system known to host transiting planets around both of its stars." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

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 gained new insight into the formation of planets around twin stars that orbit one another. Despite the fact we are most familiar with planets orbiting a single, central star — like ...
