Neutrino focusing

Abstract

We study the lensing of neutrinos by astrophysical objects. At the difference of photons, neutrinos can cross a stellar core; as a result the lens quality improves. While Uranians alone would benefit from this effect in the Sun, similar effects could be considered for binary systems.
