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 ...

Some 200 light years from Earth, the core of a dead star is circling a larger star in a macabre cosmic dance. The dead star ...

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 ...

White dwarfs, the glowing cores of dead stars, often host disks of dusty debris. However, these debris disks only appear 10-20 millions of years following the star’s violent Red Giant phase. A new ...

NASA’s Hubble Space Telescope is providing strong evidence that white dwarfs, the burned-out relics of stars, are given a “kick” when they form. The sharp vision of Hubble’s Advanced Camera for ...

A white dwarf star is undergoing the process of turning into a “cosmic diamond” as it begins to crystalise. The lullaby “Twinkle Twinkle Little Star” talks about stars in the sky looking like diamonds ...
