White dwarf seen switching on & off for the 1st time: Astronomers

  • Researchers led by Durham University have seen a white dwarf abruptly switching on and off for the first time
  • The white dwarf observed by the team is known to be accreting, or feeding, from an orbiting companion star
  • Astronomers saw it lose brightness in 30 minutes, a process which has earlier been observed to occur over several days to months
