Скачать или смотреть White Dwarf Star Caught Eating Its Planets! LSPM J0207+3331 Challenges Stellar Evolution Theories

Astronomers have discovered a white dwarf star, LSPM J0207+3331, still actively consuming remnants of its planetary system. Located 145 light-years away, this 3-billion-year-old stellar remnant is surrounded by a debris disk rich in minerals like sodium, magnesium, and iron. This finding challenges our understanding of late-stage stellar evolution, suggesting that white dwarfs may retain planetary remnants undergoing dynamical changes long after the star’s death. The discovery was made using the W. M. Keck Observatory and published in The Astrophysical Journal Letters. Learn how this polluted white dwarf provides insights into the fate of our own Solar System and the role of gravitational disruptions in planetary systems.
