Neutrinos from the Earth, Sun and Nearby Neutron Stars

Neutrinos are undeniably an exciting avenue in the pursuit of physics beyond the Standard Model, with a rich upcoming experimental programme and a plethora of new phenomena tied to both their mass generation and potential dark matter interactions. In this talk I will discuss scenarios where the weak interaction strength of neutrinos can be leveraged to gain sensitivity to processes deep inside stellar environments. More concretely this entails the following two-part talk:
1. Evaporating black holes in the Sun and Earth and their associated neutrino signatures.
2. Preliminary work looking into the role of muon diffusion and associated neutrino emission in neutron star cores.
