dc.description.abstractWe study the consequences on the neutrino oscillation parameter space, mixing angle (tan(2)theta) vacuum mass difference (Delta m(0)(2) when mass varying neutrino (MaVaN) models are assumed in a supernova environment. We consider electronic to sterile channels) nu(e) -> nu(s) and (nu) over bar (e) -> (nu) over bar (s) in two-flavor scenario. In a given model of MaVaN mechanism, we induce a position-dependent effective mass difference, Delta(m) over tilde (2)(r) where r is the distance from the supernova core, that changes the neutrino and antineutrino flavor conversion probabilities. We study the constraints on the mixing angle and vacuum mass difference coming from r-process and the SN1987A data. Our result is the appearance of a new exclusion region for very small mixing angles, tan(2)theta = 10(-6)-10(-2) and small vacuum mass difference, Delta m(0)(2) = 1-20 eV(2), due the MaVaN mechanism.en
