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 ...

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 ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

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 research suggests Einstein's general relativity explains the rarity of planets orbiting two suns. In tight binary systems ...

An international team of researchers has just revealed the existence of three Earth-sized planets in the binary stellar system TOI-2267 located about 190 light-years away. This discovery, published in ...

Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.

In theory, hundreds of circumbinary planets should have been detected by missions such as NASA’s Kepler and TESS space ...

One such mystery, described in a recent paper in The Astrophysical Journal Letters, concerns circumbinary exoplanets—or rather, the shortage thereof—in the now 6,000+ exoplanets confirmed to date.

A team of astronomers observed a confused exoplanet orbiting its two parent stars in a highly unusual way. As New Scientist reports, the planet, which was first discovered in 2004, is located in a ...

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.
