As a free, intensive, rarely interactive, and well directional messenger, solar neutrinos have
been driving both solar physics and neutrino physics developments for more than half a …

For centuries the heavens have been a natural laboratory to test the classical laws of motion,
and more recently to test Einstein's theory of gravity. Today, astrophysics has become a vast …

Solar neutrino studies triggered and largely motivated the major developments in neutrino
physics in the last 50 years. The theory of neutrino propagation in different media with matter …

When hypothetical neutrino secret interactions (ν SI) are large, they form a fluid in a
supernova (SN) core, flow out with sonic speed, and stream away as a fireball. For the first …

Neutrino-neutrino scattering could have a large secret component that would turn neutrinos
within a supernova (SN) core into a self-coupled fluid. Neutrino transport within the SN core …

The evolution of a supernova core can be dramatically different if the neutrinos trapped in
the core mix and/or flip helicity and escape as" sterile, right-handed" neutrinos. Thus the …

Despite the fact that the solar neutrino flux is now well understood in the context of matter-
affected neutrino mixing, we find that it is not yet possible to set a strong and model …

We study the possibility that a keV-MeV mass hidden photon (HP), ie a hidden sector U (1)
gauge boson, accounts for the observed amount of dark matter. We focus on the case where …

The oscillation of neutron n into mirror neutron\(n'\), its mass degenerate partner from dark
mirror sector, can gradually transform the neutron stars into the mixed stars consisting in part …

In the present lectures the following topics are considered: general properties of neutrinos,
neutrino mass phenomenology (Dirac and Majorana masses), neutrino masses in the …
