In 2017, astronomers found hypervelocity stars believed to have come from the Large Magellanic Cloud, supposedly kicked out of binary systems by supernovae. What kept the surviving star from being ...

Is it a two-for-sun deal. Astronomers were blown away after discovering a bizarre exoplanet that orbits twin stars closer than any ever seen before in a binary star system, per a starry study ...

Astronomers have made a groundbreaking discovery of three Earth-sized planets orbiting within a compact binary star system. This rare configuration, where planets circle two stars simultaneously, ...

Stars are the fundamental building blocks of our universe. Most stars host planets, like our sun hosts our solar system, and if you look more broadly, groups of stars make up huge structures such as ...

Using NASA's Kepler space telescope, Chinese astronomers have observed a binary star system known as KIC 5623923. As a result, they found that the investigated system is a faint eclipsing binary ...

A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

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 ...

Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...

Interacting binary stars, a class of stellar systems consisting of two gravitationally bound stars, exhibit a rich diversity of phenomena driven by mass transfer and angular momentum exchange. In many ...

Contact binary stars are systems in which both stellar components share a common envelope, resulting in complex interactions and energy transfer. These systems exhibit characteristic light curves that ...
