Radiation Pressure

Final measurements made. Here are related plots:

Charge Exchange

Compiles, runs, and does something. Need to test it — possibly determine steady-state mixing ratio for some density? Also still seeing that excess neutral square behind the ablated planet material. It almost looks like the recombination shadow we see in the other simulations, but since we don't have any ionizing radiation I don't see what would maintain the completely ionized state outside that region (perhaps it's not actually complete?). Could also be from some mixing, or more time spent there by the stellar wind… thoughts?

Uses HD209458b parameters, as given in ​this post.

AMR line transfer

Made good progress last Wednesday. Latest commit just has a short to-do list, mostly cleanup. Primary functional code left is implementing an MPI derived type for sends and receives of rays, and a custom scatter and gather (because of differing array sizes).
