Current and recent projects
Modeling TCF-driven chromospheric evaporation
My most active project involves
developing a 1-D hydrodynamic ("shocktube") model to
study chromospheric evaporation driven by thermal conduction in a
flaring loop. To do this, I use a one-fluid hydrodynamic shock,
which is formed when a coronal loop contracts due to magnetic tension
after a reconnection event. This shock then develops a thermal
conduction front, which deposits energy into the chromosphere, driving
both upflows ("evaporation") and downflows ("condensation").
to see some results from the model.
In the near future, I plan to use thius model to extend the work by Guidoni & Longcope (2010)
on shocks formed in a reconnected retracting thin flux tube. Dr.
Guidoni's code generates the shocks in a dynamic retracting loop, but
cannot easily handle the transition region or chromosphere. My
code will thus serve as an attachment to the end of the thin flux tube,
and be driven by the boundary conditions.

I grew up in a little town called Paradise in northern
California. I did ballet, and also
shot at things. I got my undergraduate at Dickinson College in
Carlisle PA. I didn't originally go there for Physics, but that's
what I got anyway. Now I'm pursuing my Ph.D.
in Solar Physics in Bozeman MT.
