Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...
Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of ...
Binary star systems may help giant planets form more easily by triggering planet formation far from their stars.
Our sun is a bit of an outlier in the general stellar population. We typically think of stars as being solitary wanderers ...
New simulations suggest binary star systems may be ideal for planet formation, and may produce more gas giants than single-star systems.
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 ...
