Overview
- The Dark Dwarfs hypothesis published in JCAP proposes that low-mass objects in dark matter–rich regions glow via annihilation of heavy WIMPs rather than nuclear fusion
- Only self-interacting, massive particles like WIMPs can accumulate inside brown dwarfs and produce the energy signature defining dark dwarfs
- Retention of lithium-7 is identified as a definitive spectral marker, since this isotope is rapidly destroyed in ordinary stellar and sub-stellar objects
- Teams will use JWST’s infrared sensitivity to hunt for extremely cold objects at the Galactic Center exhibiting lithium-7 absorption features
- Complementary statistical studies of brown dwarf populations aim to reveal a hidden dark dwarf cohort, though no candidates have yet been confirmed
