24. Solar and stellar differential rotation and dynamo, mean-field vs. global models

Contributed by Gustavo Guerrero. Posted on July 30, 2014

Numerical simulations of solar rotation and dynamo have been performed over the last decades with the aim of understanding the physics of the solar interior.  Here we briefly discuss two main approaches, namely, mean-field modeling and global simulations. We also present recent results of hydrodynamic global simulations which reveal interesting aspects of stellar rotation.

20. Solar Meridional Flow in the Shallow Interior during the Rising Phase of Cycle 24

Subsurface meridional flow speed shows an anti-correlation with the magnetic flux being transported poleward above the latitude of 35&#176. In the lower latitude, the residual meridional flow, after a long-time mean profile is subtracted, shows converging flow toward the activity belts.
