Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of ...
Astronomers have long faced a strange contradiction: most stars are born in pairs, and ...
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.
In theory, hundreds of circumbinary planets should have been detected by missions such as NASA’s Kepler and TESS space ...
In theory, it could happen – one of the very first solutions to the three-body problem was this scenario. But it is very unlikely to be stable over time. You need the stars to have near equal mass and ...
Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue straggler stars, ...
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 ...
