Jupiter-Mass Exoplanet Found Orbiting White Dwarf

  • Using a technique called gravitational microlensing, which occurs when a star close to Earth momentarily aligns with a more distant star, astronomers discovered a giant exoplanet in a Jupiter-like orbit around a white dwarf star. Located at approximately 2,000 parsecs (6,523 light-years) towards the center of our Milky Way Galaxy, this system is likely to represent an analogue to the end stages of the Sun and Jupiter in our own Solar System.

The Fastest-spinning White Dwarf ever Seen Rotates Once every 25 Seconds

  • The sun turns once a month and the Earth once a day, but a white dwarf star 2,000 light-years away spins every 25 seconds, beating the old champ by five seconds. That makes it the fastest-spinning star of any sort ever seen — unless you consider such exotic objects as neutron stars and black holes, some of which spin even faster.
  • The fast-spinning white dwarf, named LAMOST J0240+1952 and located in the constellation Aries, got in a whirl because of its ongoing affair with a red dwarf star that revolves around it. Just as falling water makes a waterwheel turn, so gas falling from the red companion star made the white dwarf twirl.
