abstract
Dark matter may be discovered through its capture in stars and subsequent annihilation. It is usually assumed that dark matter is captured after a single scattering event in the star, however this assumption breaks down for heavy dark matter, which requires multiple collisions with the star to lose enough kinetic energy to become captured. We analytically compute how multiple scatters alter the capture rate of dark matter and identify the parameter space where the affect is largest. Using these results, we then show how multiscatter capture of dark matter on compact stars can be used to probe heavy ($m_X >$ TeV) dark matter with remarkably small dark matter-nucleon scattering cross-sections. As one example, it is demonstrated how measuring the temperature of old neutron stars in the Milky Way's center provides sensitivity to high mass dark matter with dark matter-nucleon scattering cross-sections smaller than the xenon direct detection neutrino floor.

Neutron stars can shine a light on elusive lepton-flavor-violating dark matter
Flavor blocking keeps lepton-flavor-violating dark matter from thermalizing inside neutron stars, so p-wave annihilation stays efficient and heats the star to observable temperatures.

High-Energy Neutrinos from Black Hole Evaporation in Neutron Stars
Repeated collapse of asymmetric dark matter inside neutron stars into evaporating microscopic black holes can produce a Galactic-Center-concentrated high-energy neutrino flux at the 10^-12 GeV cm^-2 s^-1 level, subdom...

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.

Dark Matter Capture in Supernovae Modifies Dark Photon Cooling Bounds
Asymmetric dark matter captured in SN progenitors can form a 'dark photosphere' that traps dark photons and reopens SN1987A-excluded parameter space.

Can Orbital Decay of Accreting Binary Pulsars Probe Dark Matter?
Dark matter accretion onto binary pulsars is far too weak to affect observed orbital decay, so existing pulsar timing data cannot probe dark matter microphysics.
