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 ...

At the 244th meeting of the American Astronomical Society (AAS), researchers unveiled findings from a pioneering high-angular resolution program that sheds new light on the process of planet formation ...

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 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 ...

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 -- ...

Deep within the Orion Nebula, researchers are one step closer to understanding how Jupiter-mass binary objects (JuMBOs) form—a longstanding mystery in astrophysics The recent discovery of JuMBOs in ...
