GoKawiilAstronomers find signs of second-generation planet at white dwarf HS 0209+0832
Reanalyzing 1999 Hubble data with an updated chemical database, University of Warwick-led researchers identified roughly 100 previously unexplained chemical signatures around white dwarf HS 0209+0832 as niobium, an element formed only in extreme stellar conditions. Niobium levels were about 1,000 times higher than in our sun, which the team says points to a planet formed from material shed by the dying star itself rather than from its original birth cloud.
