Semi-conservative reduced speed of sound technique for low Mach number flows with large density variations
H. Iijima, H. Hotta, S. Imada
The reduced speed of sound technique (RSST) has been used for efficient simulation of low Mach number flows in solar and stellar convection zones. The basic RSST equations are hype…
Asteroseismic detection of latitudinal differential rotation in 13 Sun-like stars
O. Benomar, M. Bazot, M. B. Nielsen +7
The differentially rotating outer layers of stars are thought to play a role in driving their magnetic activity, but the underlying mechanisms that generate and sustain differentia…
Breaking Taylor-Proudman balance by magnetic field in stellar convection zone
H. Hotta
We carry out high-resolution calculations for the stellar convection zone. The main purpose of this study is to investigate the effect of a small-scale dynamo on the differential r…
Sunspot Drawings by Japanese Official Astronomers in 1749-1750
Hisashi Hayakawa, Kiyomi Iwahashi, Masashi Fujiyama +7
Sunspot observations with telescopes in 18th century were carried out in Japan as well. One of these sunspot observations is recorded in an account called Sansaizusetsu narabini Ka…
