  It is suggested that the nonorthodox model of a quasar as a neutrino ball
described in terms of the standard model extended by adding right-handed
neutrinos and the Majorana scalar field can be presented in order to explain a
quasar as a body of weak interacting neutrinos. Neutrino interaction with the
scalar Majorana field violates the lepton number and produces the mass
splitting of the neutrino due to the sea-saw mechanism. In this model a quasar
is an object which appears in the result of the first order cosmological phase
transition. In this interpretation a quasar may be regarded as a ball filled
with Dirac neutrinos and can be treated as a remnant of phase transition with
unbroken global lepton symmetry. In this paper we study the macroscopic
parameters of such a configuration. In the result the mass-radius curve M(R)
for the quasar is obtained.
