Red dwarf gas giants defy formation theory

A Jupiter‑size planet (TOI‑5205b) orbits a very small red dwarf, yet its atmosphere shows lower heavy‑element abundance than expected and even lower metallicity than the host star. The team (Kanodia et al.) used TESS transits and atmospheric retrievals to infer that heavy elements may have migrated to a dense interior that doesn't mix with the envelope, contradicting standard core‑accretion expectations for low‑mass stars. — If confirmed, this forces revisions to planet‑formation theory, alters expected exoplanet demographics around common red dwarfs, and changes priorities for telescope searches and interpretation of biosignature prospects.
