Particle transport in solar type stars

摘要: The potential effects of three particle transport processes on solar evolution are discussed. Even though its effect is not very large, atomic diffusion should in principle be included the standard model. It increases neutrino flux. Turbulent could significantly reduce No reliable estimate strength turbulence has been made from first principles. Its 3He, Li and Be abundance A model with Re*≂50 may sufficiently flux while being compatible constraints imposed by abundances oscillation spectrum. This remains to shown detailed calculations.Such a low value implies that core spinning at least times faster than surface. To rotation rate would require more needed observed value.The parametrization constant Re* arbitrary. real value...
