Astronomers discovered a metal-concentrated "scar" on a white dwarf star, 63 light years from Earth, caused by its magnetic field during the cannibalization of planets and asteroids.

Astronomers have discovered a unique "scar" on a white dwarf star, the remnant of a star like our Sun. The scar, a concentration of metals, was found on the surface of the white dwarf, which is around 63 light years from Earth. The research, published in The Astrophysical Journal Letters, reveals that the star's magnetic field plays a key role in the process, resulting in a scar on the white dwarf's surface. This is the first time a star's "scar" has been observed due to the cannibalization of planets and asteroids.
