Update 3/15

Exoplanets II abstract:
Using AstroBEAR, a 3D MHD fluid dynamics simulation code, we have developed a new platform on which to study the dynamics of planetary winds, including a variety of microphysics such as ionization heating, radiation pressure, and charge exchange. We will present the results of a study of the effects of planet mass and stellar flux on the structure of hot Jupiter winds, as well as changes to this structure that result from introducing radiation pressure.

​WASP-12b paper sent out to authors for review of referee response.

​Parameter space paper coming along. First cut of methods done, with a start on results. How much repetition is appropriate for figure captions/commentary? Intro is next on list of things to write.

Related, running out of space on BlueHive again. My personal quotas are full on BlueStreak (could request more - only have 200 GB here), BlueHive, and Stampede, and afrank_lab is full on BlueHive. We could back up and remove all but the final frames of the four low-flux cases (do we need the low-flux, high-density, low-pressure test for anything?).

On the simulations, the low-pressure ambient test for Run5 is proceeding nicely. The low-pressure ambient tests are running significantly faster than the higher-pressure ones - something to keep in mind when designing future planet simulations.

This seems to indicate a problem. Running a couple of tests indicates that there's no radiation pressure in the first dozen or so steps, and the flux is zero throughout the grid, so it may just be that we haven't reached a steady state yet in Run2 (on further consideration, though, this doesn't seem likely to be the case - Run2 looks very stable between frames ~120 and 150, at least).

Two possible tests spring to mind - let test run go further with debug output in the line transfer routines, or run Run2 further with iLineTransfer=1, see if the same thing occurs. Some minor parts (that shouldn't matter on a restart) were changed between the original run and the radiation pressure run, primarily the number of zones between the outer boundary and the zero radius.
