WD J1330+6435: Scientists have found a green dwarf in space

Der SpiegelIndependentCenter5 hr. ago

Astronomers have discovered a green dwarf star named WD J1330+6435 in the constellation Dragon, approximately 280 light-years away from Earth. This star appears green due to unique atmospheric conditions caused by high density and interactions between sodium atoms and helium atoms, which alter the absorption of light wavelengths. Unlike typical white dwarfs, which appear white or similar to other stars, this discovery highlights rare changes in chemical composition affecting color perception. The study, published in 'RAS Techniques and Instruments,' examined 151 nearby white dwarfs and found that WD J1330+6435 has enriched outer layers with elements like calcium, lithium, and sodium, contributing to its unusual green hue. While green stars are common in science fiction, this marks the first documented example in reality.

Astronomers have successfully determined the colors of white dwarf stars, which were previously undetectable by telescopes. The findings reveal a greater diversity of colors than expected, challenging previous assumptions about these stellar remnants. This discovery could provide new insights into the composition and evolution of white dwarfs. The research highlights the importance of advanced observational techniques in astronomy.
