That thinning likely resulted from two stars merging and burning off outer layers during the collision. This rare white dwarf merger left a stripped remnant with a nearly pure hydrogen atmosphere yet ...
University of Warwick astronomers have uncovered compelling evidence that a nearby white dwarf is in fact the remnant of two stars merging—a rare stellar discovery revealed through Hubble Space ...

Earth-size stars and alien oceans – an astronomer explains the case for life around white dwarfs
The Sun will someday die. This will happen when it runs out of hydrogen fuel in its core and can no longer produce energy through nuclear fusion as it does now. The death of the Sun is often thought ...

A 3-billion-year-old white dwarf, the core of a dead star, consumed an exoplanet from its former planetary system. Credit: NASA / ESA / Joseph Olmsted illustration A dead star core about 145 ...
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 ...
Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and ...
A rare white dwarf merger remnant emerges in ultraviolet light, revealing thin layers of hydrogen and helium stripped away during a cosmic collision. Scientists at the University of Warwick report the ...
