31. The Photospheric Size-Flux Distribution and its Relationship with the Small-Scale and Global Components of the Solar Dynamo

Contributed by Andrés Muñoz Jaramillo. Posted on October 31, 2014

Taking advantage of 11 different databases, we use statistical analysis to probe the nature of photospheric magnetic structures. We find evidence of two separate mechanisms at play, and propose that they are directly connected to the global and small-scale components of the solar dynamo.

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.

17. Is the recent discovery of the multi-cell meridional circulation a threat to the flux-transport dynamo?

Motivated by recent observations we have explored whether the flux-transport dynamo model can work with multi-cell meridional flow. We find that it can work when certain conditions are fulfilled.
