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 a giant planet orbiting a tightly bound pair of young stars, marking a first in direct exoplanet imaging. The planet, known as HD 143811 AB b, is the closest-in world ever ...

Washington DC — New theoretical work shows that gas-giant planet formation can occur around binary stars in much the same way that it occurs around single stars like the Sun. The work is presented ...

A research team has used both archival Hubble Space Telescope data and new observations to precisely measure the binary star system NGC3603-A1. One star weighs about 93 times the mass of our sun, ...

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 ...

What can binary stars comprised of two different types of stars teach astronomers about stellar evolution? This is what a recent study published in The Astrophysical Journal hopes to address as a team ...

At the centre of the Milky Way is a supermassive black hole called Sagittarius A*. It is roughly 27,000 light years from Earth and 23.5 million kilometres in diameter. In a world first, a team of ...

Astrophysicist Tomoaki Matsumoto and collaborators have used three-dimensional magnetohydrodynamic supercomputer simulations ...
