“Astronomers discover first green star and the reddest star ever recorded”
Astronomers spotted a green white dwarf and the reddest white dwarf recorded.
Key points
- Researchers studied white dwarfs to understand unexpected colors beyond white, blue, and orange.
- Green color result comes from high atmospheric density interacting with trace elements like sodium.
- WD J1330+6435 appears chartreuse green due to calcium, lithium, sodium enrichment.
- WD J1011+2845 is proposed as the reddest star with carbon distortion in its light.
- Colors were inferred from spectra and computer models, not direct eye observations.
