Electromagnetic properties of neutrinos and phenomenology of neutrino oscillations

Neutrinos are one of the most intriguing particles of the Standard Model. The observation of oscillation among different neutrino flavors suggest the existence of an extended theory beyond the Standard Model. These extended theories have several new phenomenological features which might be detected in future neutrino experiments. One such possibility is the existence of neutrino electromagnetic interactions. Despite being electrically neutral, neutrinos acquire their electromagnetic properties through interaction with photons at quantum loop level. This can generate important new effects such as neutrino spin-flavor oscillations in the presence of background electromagnetic fields. In the present thesis, we study the phenomenology of neutrino flavor and spin-flavor oscillations in solar and astrophysical environments
