Azaymi Litzi Siu Tapia is currently a PhD student in Solar Physics at Max Planck Institute for Solar System Research and the University of Gottingen in Germany, since August 2014. She is working with Andreas Lagg and Sami K. Solanki on the physical mechanisms responsible for driving photospheric flows in the penumbra of sunspots.
Azaymi is from Mexico, she graduated in Physics from the Faculty of Sciences in the National Autonomous University of Mexico (UNAM). She also received a master's degree on Space Physics from UNAM, with a master's thesis on waves and plasma instabilities growing inside magnetic clouds and complex structures that propagate in the solar wind.
For her current doctoral project, Azaymi has been analyzing spatially coupled inversion results of the Hinode spectropolarimetric data (SOT/SP) of a sunspot that shows an anomalous counter Evershed flow in their penumbra. More recently, she has started a collaboration with Matthias Rempel from HAO, who has simulated a sunspot with counter Evershed flows in its penumbra, very similar to what Azaymi has been studying with the observational data.
During August-September, Azaymi was visiting HAO to work jointly with Matthias Rempel in analyzing the results of his high-resolution sunspot simulations, which are based on the MuRAM radiative MHD code. During Azaymi's visit to HAO, they will try to reveal the physical mechanisms driving the counter Evershed flows in the simulations, which will give them a better insight about what drives such anomalous flows in the Sun.
