Bc. Chauhan et al., RSFP PREDICTIONS FOR TRANSVERSE SOLAR MAGNETIC-FIELD DISTRIBUTION FROM SOLAR-NEUTRINO DATA, Modern physics letters A, 13(15), 1998, pp. 1163-1170
Even though the standard solar model (SSM) has been very successful in
predicting the thermal and nuclear evolution of the Sun, it does not
throw enough light on solar magnetic activity. In the absence of a gen
erally accepted theory of solar dynamo, various general arguments have
been put forth to constrain solar magnetic fields. In the absence of
reliable knowledge of solar magnetic fields from available astrophysic
al data, it may be worthwhile to constrain the solar magnetic fields f
rom solar neutrino observations assuming Resonant Spin-Flavor Precessi
on (RSFP) to be responsible for the solar neutrino deficit. The config
uration of solar magnetic field derived in this work is in reasonably
good agreement with the magnetic field distribution proposed by Akhmed
ov et al. (Sov. Phys. JETP 68, 250 (1989)). However, the magnetic fiel
d distribution in the radiation zone used by Pulido (Phys. Rep. 211, 1
67 (1992)) is ruled out. The magnitude of the magnetic field in the ra
diation and convective zones of the Sun are very sensitive to the valu
e chosen for the neutrino magnetic moment. However, any change in the
value of neutrino magnetic moment does not affect the magnetic field d
istribution as it only scales the magnetic field strength at different
points by the same amount.
