Warwick Study Predicts Green and Pink Hues for Some White Dwarfs
Researchers at the University of Warwick reported that their atmospheric models predict some white dwarfs could appear pale green or salmon pink, depending on elements such as sodium and calcium, according to Defector. The study builds on earlier modeling that identified a spectrum of possible hues, from green to pink, in white dwarf atmospheres, as described by Phys. org. Later observations confirmed the first green-glowing white dwarf, WD J1330+6435, located 326 light-years away, with the green hue attributed to sodium from planetary debris, a finding reported by Newser. Additional analysis also highlighted the pinkest known white dwarf, expanding the range of colors that these dense stellar remnants may exhibit.
The initial modeling work, published by Phys. org, outlined how variations in atmospheric density and composition could shift the visible color of white dwarfs across a broad palette. Subsequent spectral analyses, covered by Nautilus and ComicBookMovie. com, corroborated the presence of sodium and calcium as key agents producing the unusual green and pink tones observed in the newly identified stars.
