"Dead Star's Fate Predicts Sun's Destiny in Cosmic Graveyard"
Astronomers have studied a dead star, a white dwarf, located in the open star cluster Messier 37, which is around 4,500 light years from Earth. This study could reveal how the star died and provide insights into the fate of our own sun in around 5 billion years. By studying a dead star in this cluster, scientists can better understand how stars of the same age evolve and die, helping to test theories of stellar evolution. The researchers also determined the chemical composition of the white dwarf, finding it strangely lacking hydrogen on its surface, indicating a violent event in its past. Understanding the initial-final mass relation is crucial for determining a star's lifespan and its final phase, whether it be a white dwarf, neutron star, or black hole.
