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
Circinus youngest member of a class of objects known as "X-ray binaries" has been found. Researchers found that the neutron star in Circinus is less than years old, making the X-ray binary much younger than any other known in the Milky Way.
This extraordinary image shows one of the highest excitation nebulae in the Magellanic Clouds (MCs), two satellite galaxies of our own Milky Way. is a binary star, consisting of one WR-star — highly evolved massive star - and.
In an eclipsing binary star system like Algol, the total starlight received from a pair of neighboring stars dips whenever the dimmer star crosses in front of the brighter partner. Only systems in which the orbits are oriented edge-on to Earth yield the light curve shown at the bottom. The reduction in brightness during the secondary-eclipse geometry is normally much more subtle than shown here.
