The runaway star J1249+36 is speeding through our galaxy at a million miles an hour, fast enough to escape its gravitational pull. Theories suggest it was either ejected by a supernova explosion of a white dwarf or by the dynamics of a black hole binary in a globular cluster. Researchers aim to study its elemental composition to determine its origin.
A massive "zombie" star, known as a white dwarf, has been observed moving at a speed of 22,000 miles per hour relative to the Hyades star cluster. This runaway white dwarf is providing valuable insights into the mysteries surrounding the cluster and the formation of white dwarfs. The discovery suggests that open star clusters may produce ultramassive white dwarfs more commonly than previously thought. The research, based on data from the Gaia spacecraft, has been accepted for publication in The Astrophysical Journal.
