The author solved, for the first time, one of the long-standing issues in solar physics, i.e., the maintenance mechanism of the solar differential rotation in the near-surface shear layer. The author attacked this problem with a newly developed approach, the reduced speed of sound technique, which enabled him to investigate the surface and deep solar layers in a self-consistent manner. This technique also made it possible to achieve an unprecedented performance in the solar convection simulations for the usage of the massively parallel supercomputers such as the RIKEN K system. It was found that the turbulence and the mean flows such as the differential rotation and the meridional circulation mutually interact with each other to maintain the flow structures in the Sun. Recent observations by helioseismology support the author's proposed theoretical mechanism. The book also addresses the generation of the magnetic field in such turbulent convective motions, which is an important step forward for solar cyclic dynamo research. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aSpace sciences 606 $aPlanetary science 606 $aSpace Sciences (including Extraterrestrial Physics, Space Exploration and Astronautics)$3https://scigraph.springernature.com/ontologies/product-market-codes/P22030 606 $aPlanetology$3https://scigraph.springernature.com/ontologies/product-market-codes/G18010 615 0$aSpace sciences. 615 0$aPlanetary science. 615 14$aSpace Sciences (including Extraterrestrial Physics, Space Exploration and Astronautics). 615 24$aPlanetology. 676 $a536.2012 700 $aHotta$b Hideyuki$4aut$4http://id.loc.gov/vocabulary/relators/aut$0792820 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910300436103321 996 $aThermal Convection, Magnetic Field, and Differential Rotation in Solar-type Stars$91773058 997 $aUNINA
