The neutrino star in the bulk Universe
R. Manka, D. Karczewska
Abstract
Motivated by the Kaluza-Klein theory with large extra spacetime dimensions the neutrino star built from the massive sterile neutrinos core and the massless brane neutrinos envelope is presented. The six - dimensional compactification scale ~15 MeV gives the maximal neutrino mass Mmax = 2.3 104 of the solar mass with the radius Rmax = 1.2 106 km . The maximal neutrino star parameters varies with temperature. In the limit of the neutrino ball approximation the maximal sterile neutrino star is Mmax = 1.1 106 of the solar mass.
