Astronomers Discover Potential “Phoenix Planet” Around A Dead Star

Researchers also detected unusual levels of niobium in the white dwarf’s atmosphere, potentially indicating that material from nearby debris has accumulated there.

Astronomers at the University of Warwick have reported evidence of a potential “phoenix planet” orbiting the white dwarf HS 0209+0832. The candidate could represent a rare second-generation planet formed from debris released during its star’s final stages.

Unlike planets such as Earth, which form alongside young stars, second-generation worlds may emerge from material left behind after stellar evolution. Data from NASA’s TESS mission suggests the candidate is a gas giant orbiting its host every 4.4 days.

💡
The discovery remains unconfirmed, and the candidate is considered too hot to support life. Scientists plan to observe the system with the James Webb Space Telescope over the coming year to investigate the evidence further.

If confirmed, the finding could expand our understanding of planetary formation and the possible fate of planetary systems after their stars die.
