Fuel-exhausted white dwarf stars are 'binge eaters': Study
A UK-based study has found that white dwarfs gain mass in distinct bursts where they "binge eat" matter from nearby stars. White dwarfs are Earth-sized objects having mass equal to the Sun that have exhausted their nuclear fuel. Using NASA's Kepler Space Telescope, scientists found sporadic magnetic accretion disks around white dwarfs, considered "non-magnetic", which could explain the behaviour.
