Hubble data suggest a white dwarf may host a second-generation planet
NASA says unusual chemical abundances in HS 0209+0832 point to a possible planet formed from material shed by the star.
- NASA says the study was published in Nature Astronomy.
- The proposed planet is not confirmed; NASA describes it as a possible explanation for the chemical clues.
The finding raises the possibility that planets can form around stellar remnants from material expelled by their stars.
A little more context
NASA reports that researchers revisited archived Hubble data for the white dwarf HS 0209+0832 and found unusual chemical abundances they interpret as evidence for a possible second-generation planet. The study was published in Nature Astronomy.
NASA describes a white dwarf as the remnant core of a low-mass star that has used its nuclear fuel and lost its outer envelope of gas and dust. A second-generation planet would form around the remnant from that expelled material. The evidence does not confirm that a planet exists.

NASA says chemical clues in HS 0209+0832 suggest a possible, unconfirmed planet formed from material shed by its star.
Left
A possible planet forming from expelled material could prompt questions about how scientific research explains the origins of planetary systems.
Center
The proposed explanation remains unconfirmed, so interpretation should distinguish the chemical evidence from the possibility of a planet.
Right
The finding could highlight how research into stellar remnants expands understanding of planetary formation without establishing that this planet exists.
