Fluctuations in stellar nuclear reaction-diffusion system
摘要
Abstract
Fluctuations in stellar nuclear reaction-diffusion system affected by the gravity-temperature gradient effect are investigated and the oscillations related to the fluctuations of particle number density in the proceedings of the core nuclear reactions of stars are analyzed. It is shown that there are a series of fluctuation waves propagating in space and oscillations of particle number density in stellar cores, while the gravity-temperature gradient effect is responsible for producing the oscillations. These oscillations inside stars may lead to time oscillating of stellar nuclear energy generating. The production of the 8B and 7Be neutrino fluxes might not only be suppressed due to the nonlinear density enhancement of 3He but also be changing with time due to the oscillations of 3He.关键词
