Christine's Visit

==============

Attached is an ApJ letter that I've published on my experiment and the astrophysical motivation for it. What I would like to do with AstroBEAR is create the Cataclysmic Variable (CV) detailed in the first paragraph of the introduction. The CV related to this work is considered non-magnetic because the secondary star in the binary system donates mass to the white dwarf (WD) in the orbital plane, (not along field lines to a polar axis).

The localized area of interest is the collision region at which the accreting stream impacts the formed accretion disk around the WD. I've also attached an ApJ paper that did simulations on this (comparing isothermal and adiabatic EOS's) because they detail parameters of the CV system. You will see in my paper the connection of this astrophysical system to my laser experiment, but to re-iterate the "problem I want to solve" is the dynamics of the shocked stream at the accretion disk edge. I have new data, which I showed to your group in July, that hasn't been published yet, but shows perhaps some stagnation and a diverted stream in an oblique shock scenario. This corresponds most likely to some optical thickness in the shock system, so it would be interesting to do the CV simulation looking more closely at the shocks that form in it and how mass moves around the collision region, as a function of scale height of the disk.

I can offer more details with questions/concerns, but my paper in combination with the Armitage and Livio one (sections 1 through 2.3) offer a good overview of the system.

I am currently on a different experiment in Livermore, but I am going to start exploring the AstroBEAR wiki, etc, this week! Thank you for setting up an account for me.
