# Froggit: Astronomical discoveries reported through October 23, 2026 **White dwarf may host a “second-generation” planet — October 5.** A study of HS 0209+0832 found unusual atmospheric abundances, including zinc, copper, and niobium, alongside little silicon and no detected iron. TESS data showed a 4.399-day brightness variation. The authors interpret the evidence as consistent with a planet formed from material expelled by the star, but describe it as a *candidate*; the variation could also come from a cometary tail.
