Debris from Disintegrating Planets Hurtling into White Dwarfs across the Galaxy

An impression of the high-mass X-ray binary called Cygnus X-1. It consists of a blue supergiant star (right) called HDE 226868, orbiting what is in all likelihood a black hole. The black hole is sucking gas from the blue star’s atmosphere, leading to the formation of an accretion disc around the black hole.

The moment that debris from destroyed planets impacts the surface of a white dwarf star has been observed for the first time by astronomers at the University of Warwick.

They have used Xrays to detect the rocky and gaseous material left behind by a planetary system after its host star dies as it collides and is consumed within the surface of the star.

Published today (9 February) in the journal Nature, the results are the first direct measurement of the accretion of rocky mate...
