PHÖNIXWELT – Der Planet aus der Asche eines toten Sterns
Summary
In 1999, Hubble captured spectra of white dwarf HS0209+0832, leaving over 100 unidentified spectral lines in the archive. Decades later, researcher Jamie Williams used improved atomic data to identify niobium, copper, and zinc, revealing an unusual chemical composition inconsistent with typical asteroid debris. This anomaly, combined with a 4.4-day periodic brightness variation detected by TESS, suggests the presence of a second-generation gas giant formed from the star’s own ejected material. The planet is likely being eroded by the white dwarf’s intense radiation, creating a cycle where t…
