Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence. In those systems, the dense remnant can draw material away from ...

Astronomers from the Center of Astronomical and Space Education in Moscow report the discovery of a new star, which turned out to be an eclipsing variable binary. The finding of the new star, which received designation Grigoriev ...
The future of yellow dwarf stars, like our sun, is determined almost entirely by their mass. The most massive stars, about eight to 12 times heftier than the sun, can explode as supernovae, leading to the most extreme objects ...
