Astronomers have discovered a unique and exotic star system with a very cool methane-rich (or T-) dwarf star and a ‘dying’ white dwarf stellar remnant in orbit around each other. The system is a ‘Rosetta Stone’ for T-dwarf stars, giving scientists the first good handle on their mass and age.
The European Space Agency's XMM-Newton orbiting X-ray telescope has uncovered a celestial Rosetta stone: the first close-up of a white dwarf star, circling a companion star, that could explode into a particular kind of supernova in ... Read Post
An international team of astronomers using the National Science Foundation’s Green Bank Telescope have discovered a unique stellar system consisting of two white dwarf stars and a superdense pulsar that may provide a key clue for re... Read Post
Astronomers using the National Science Foundation's Green Bank Telescope (GBT) have discovered a unique stellar system of two white dwarf stars and a superdense neutron star, all packed within a space smaller than Earth's orbit arou... Read Post
