We carry out unprecedentedly high-resolution calculations for the solar convection zone and reproduce the solar-like differential rotation without manipulation.
The Sun is rotating differentially with the fast equator and the slow pole. This rotation profile was thought to be maintained by turbulence, but recent high-resolution calculation fails to reproduce the solar-like differential rotation profile. This problem is called the convective conundrum, which is one of the biggest solar physics problems. In our super-high-resolution calculation, we solve a part of the problem. Details of the analysis are shown in my talk.
