The early stars in the Universe are believed to have a mass between 140 to 260 times the mass of our Sun, and we didn't have evidence for this. Until now.
Scientists have finally identified fingerprints left by the explosion of 'first stars' in our UniverseThe team used data from telescopes in China and the US to uncover chemical evidence from one of the earliest stars in the universe.. Low-mass stars, like the Sun, eventually cool down and end up as white dwarfs. On the other hand, heavy-mass stars go out in a supernovae explosion and end up as neutron stars or black holes.
Their life ended in an explosion very different from the supernova explosion we know today, called theAccording to astronomers, PISNes are very different from ordinary supernovae and leave a unique chemical signature in the atmosphere of next-generation stars. Until now, these signatures have not been found.The researchers analyzed data from two high-resolution telescopes, the Subaru Telescope in Hawaii and the Large Sky Area Multi-Object Fibre Spectroscopic Telescope near Beijing.
Additionally, the iron abundance of J1010+2358 is significantly greater than that of the most metal-poor stars in the galactic halo. This indicates that the second-generation stars created in the PISN-dominated gas may be more metal-rich than anticipated.
