What to know about DESI side project reveals the spectra of disintegrated exoplanets

Astronomers used spectral data from the Dark Energy Spectroscopic Instrument (DESI) to analyze 12 metal-enriched white dwarf stars. The study found that the debris from disintegrating exoplanets accreting onto these stars contains rock-forming elements similar to those found in our own solar system.

Why it matters

Captured while DESI was unable to study its primary targets: distant galaxies, the results provide unprecedented insights into the chemical makeup of rocky exoplanets, revealing compositions remarkably similar to the planets and asteroids of our own inner…

Common ground

The results have been published in Monthly Notices of the Royal Astronomical Society.
