Generation of Solar-like Differential Rotation

We analyze the simulation result shown in Hotta & Kusano, 2021 which solar-like differential rotation is reproduced. The Sun rotating differentially with fast equator and slow pole. It widely thought that thermal convection maintains rotation, but recent high-resolution simulations tend to fail reproduce equator. This fact an aspect of one biggest problems solar physics called convective conundrum. succeed reproducing without using any manipulation unprecedentedly simulation. In this study, we data understand maintenance mechanism Our analyses lead conclusions are summarized as follows. 1. Superequipatition magnetic field generated by compression, can indirectly convert massive internal energy energy. 2. efficient small-scale transport suppresses large-scale 3. Non-Taylor--Proudman maintained entropy gradient caused anisotropic latitudinal enhanced field. 4. meridional flow mainly Maxwell stress. stress itself also has a role angular momentum for near-surface (we call it Punching ball effect). reproduced not due low Rossby number regime strong study newly finds rotation.
