  The daemon-stimulated proton decay is capable of providing an appreciable
part of the Sun luminosity as well as nonelectron flavor component in the solar
neutrino flux. This follows (1) from our experiments on detection of negative
daemons in Earth-crossing orbits, which give ~1 microsec for the decay time of
a daemon-containing proton, and (2) from an estimate of the total number of
daemons which could be captured by the Sun from the Galactic disk (up to
\~2.4E30). Because of their huge mass (~3E-5 g), the captured daemons form in
the Sun's center a kernel a few cm in size. The protons diffuse into the kernel
to decay there with a release of energy. Physically sound estimates of the
parameters of the kernel can be obtained if it consists mainly of negative
daemons. Proton decay maintains a high temperature of the daemon gas (up to
\~1E11-1E12 K), which makes it physically collisionless and prevents kernel
collapse into a black hole.
