Scientists identified the cause of the unusual single-sided pulsation of the star named HD 74423. It is located in a binary star system with a red dwarf - its close companion distorts the oscillations with its gravitational pull.
Astronomers have found a third exoplanet orbiting a binary Kepler-47 star system 3,340 light years from Earth, the first, and so far only, multi-planet circumbinary solar system discovered to date.
Scientists have discovered a giant exoplanet with a mass almost 13 times that of Jupiter in an evolved binary system. This is the first confirmation of an exoplanet in a system of this kind.
Astronomers have discovered two stars in a binary pair that complete an orbit around each other in a little over three hours, residing in the planetary nebula M3-1. Remarkably, the stars could drive a nova explosion.
Did our sun have a twin when it was born 4.5 billion years ago? Almost certainly yes -- though not an identical twin.
Scientists have found the first gamma-ray binary in another galaxy and the most luminous one ever seen.
