Particle dark matter scattering on electrons in the Sun may gravitationally capture and self-annihilate inside it to neutrinos and anti-neutrinos, or other final states that in turn decay to them. Using up-to-date measurements by…

Galactic halo neutralinos ($\chi$) captured by the Sun or Earth produce high-energy neutrinos as end-products of various annihilation modes. These neutrinos can travel from the Sun or Earth cores to the neighborhood of underground detectors…
As is well known, dark matter direct detection experiments will ultimately be limited by a "neutrino floor," due to the scattering of nuclei by MeV neutrinos from, e.g., nuclear fusion in the Sun. Here we point out the existence of a new…
Weakly Interacting Massive Particles (WIMPs) can be captured by the Earth, where they eventually sink to the core, annihilate and produce e.g. neutrinos that can be searched for with neutrino telescopes. The Earth is believed to capture…
