abstract
We present exoplanets as new targets to discover Dark Matter (DM). Throughout the Milky Way, DM can scatter, become captured, deposit annihilation energy, and increase the heat flow within exoplanets. We estimate upcoming infrared telescope sensitivity to this scenario, finding actionable discovery or exclusion searches. We find that DM with masses above about an MeV can be probed with exoplanets at DM-proton and DM-electron scattering cross sections down to about $10^{-37}$cm$^2$, stronger than existing limits by up to six orders of magnitude. Supporting evidence of a DM origin can be identified through DM-induced exoplanet heating correlated with Galactic position, and hence DM density. This provides new motivation to measure the temperature of the billions of brown dwarfs, rogue planets, and gas giants peppered throughout our Galaxy.

Complementary Planetary Spectroscopy Probes of Dark Matter
Dark matter annihilation energy deposited in planetary atmospheres and interiors, compared against existing UV airglow and heat flow measurements, yields new sub-GeV scattering constraints and long-lived mediator reach.

Can a Dark Inferno Melt Earth's Core?
Dark matter annihilation inside Earth would melt a substantial fraction of the inner core for cross sections previously allowed by surface heat-flow limits.
