Gandalf the star is a white dwarf, not a white wizard – but it's still a little magic
Two puzzling astronomical objects are white dwarfs formed by mergers of less massive white dwarfs, the discoverer of both ...

In our nearby stellar neighborhood, a burned-out star is snacking on a fragment of a Pluto-like object. With its unique ultraviolet capability, only NASA's Hubble Space Telescope could identify that ...
Astronomers have found a remarkable pair of stars that may finally prove a long-debated theory. Described in the journal Nature Astronomy, this duo offers the strongest evidence yet that type 1a ...
Visible without a telescope, γ Cassiopeiae has stood out for decades because it behaves unlike an ordinary massive star. Its X-rays are far too intense, far too hot, and far too erratic.
By Will Dunham WASHINGTON, Jan 12 (Reuters) - Astronomers have observed a white dwarf - a highly compact Earth-sized stellar ember - that is creating a colorful shockwave as it moves through space, ...

In exoplanetary science, white dwarfs are usually only an afterthought. Most extrasolar planet hunters are too busy looking for an Earth 2.0 to give these hyper-dense stellar remnants much ...
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 ...
In an ancient star system expected to be stable and dormant, scientists found a 3 billion-year-old white dwarf star still tearing apart massive quantities of rock. “The rate we’ve seen rock consumed ...
