White Dwarf Star Spirals About light-years away, two dense white dwarfs in the binary star system orbit each other once every 321 seconds. When they reach the end of their long evolutions, smaller stars typically become white dwarfs.
For the first time, researchers have detected a streamer of gas flowing from a massive outer disc toward the inner reaches of a binary star system. This never-before-seen feature may be responsible for sustaining a second, smaller disc of planet-forming m
A newly discovered planet in a binary star system located light-years from Earth is expanding astronomers' notions of where Earth-like—and even potentially habitable—planets can form, and how to find them.
Astronomers using the NASA/ESA Hubble Space Telescope, along with other telescopes on the ground and in space, have discovered a new type of exotic binary star: in the system AR Scorpii a rapidly spinning white dwarf star is powering electrons.
