Astronomers identify candidate 'phoenix planet' orbiting white dwarf HS 0209+0832

Save

Astronomers have found a possible second-generation planet circling the white dwarf HS 0209+0832. It has been nicknamed a "phoenix planet" since it may have taken shape from matter thrown off by its dying parent star. The white dwarf's atmosphere holds zinc, copper and niobium at over 1,000 times solar levels, a pattern tied to the s-process (slow neutron-capture process). The candidate is estimated at roughly Jupiter's size and completes an orbit in around 4.4 Earth days. By definition, a white dwarf is the compact leftover of a star that has used up its nuclear fuel and cast off its outer layers.
