GoKawiilStudy finds some white dwarfs glow pink, green or purple, not just white
A study published in RAS Techniques and Instruments reports that some white dwarfs display pink, green and purple hues rather than the white-to-blue colors long associated with the stellar class. Researchers attribute the unusual colors to extremely dense atmospheres—comparable to water's density and roughly a million times denser than the sun's—in which trace elements like carbon, calcium and sodium interact with helium plasma to absorb light across a broader spectrum. The study also notes that debris from shattered planets and asteroids pulled into a dying star's atmosphere can contribute these elements.
GoKawiil's interpretation of the reporting above, not reported fact.
The finding suggests astronomers may need to rethink assumptions baked into the very name 'white dwarf,' since color alone may not reliably indicate a star's composition or history. It also hints that the chemical fingerprints of destroyed planetary systems could be detectable through these color variations, potentially giving researchers a new way to study the remnants of dead solar systems. Further observation would be needed to confirm how widespread these colorful white dwarfs are.
