Evidence of a Second-Generation Planet Accreting Onto White Dwarf HS 0209+0832

A Nature study finds a white dwarf atmosphere enriched in trans-iron elements and depleted in typical rock-forming elements, consistent with accretion from a second-generation planet. The data suggest the object formed from material ejected during the progenitor star’s late stages and is now being photo-evaporated.
