The Dynamo Effect in Starsimes show cyclic reversals, like in the sun. Over the past thirty years mean-field dynamo theory has been used to explain structure and evolution of those large scale fields. The main ingredients of this theory are the alpha-effect and turbulent diffusion, but the physical nature of these effects haorganism 发表于 2025-3-27 18:54:09

Generation of the Angular Velocity Shear Near the Solar Surfacettom of the convection zone and the radiative interior. This layer manifests the transition from an almost uniform rotation in the interior to the substantial differential rotation in the convection zone. The second shear layer is right beneath the surface of the sun, where the angular velocity chanCRATE 发表于 2025-3-28 05:57:29

Nuclear Astrophysics with Radioactive Beamsnuclei produced in the environment of high temperature and density. Radioactive beams make it possible to study such reactions in the laboratory where traditional methods fail. A brief review of some of the experiments that are underway at the present and proposed for the near future is given to ill
