The first generation of solar neutrino experiments narrowed the allowed flavor mixing and mass parameter solutions (for nu_e <-> nu_x) to a few isolated regions of sin^2*2*theta - delta M^2 parameter space. Recently, the Small Mixing Angle…

In the late stages of nuclear burning for massive stars ($M>8~M_{\sun}$), the production of neutrino-antineutrino pairs through various processes becomes the dominant stellar cooling mechanism. As the star evolves, the energy of these…

We determine the neutrino spectra arising from low-mass (4-10 GeV) dark matter annihilating in the sun. We also determine the low-mass dark matter capture rates (element by element in the sun), assuming dark matter interacts either through…
