Martin's update, 6/6 '12

Disks

-20au preliminary early evo test with more resolution than before, ​http://www.pas.rochester.edu/~martinhe/2011/binary/20au-1000k-64x64x32-4amr-correctWINDdens.gif. This sim has a resolution of 64x64x32+3amr. AGB wind inflow enters the -x, +y and +-z boundaries. Improved versions of this sim should run in kraken soon.

  • 10au. Evo plots:
    • NEW http://www.pas.rochester.edu/~martinhe/2011/binary/6jun12.png
    • OLD: ​http://www.pas.rochester.edu/~martinhe/plot.pdf, these are the disk mass and the particle accretion rate, red and green respectively. Mdot (green) is higher than expected for an AGB mass-loss rate of 10-5Moyr-1, however, I found a mismatch between the wind's density at the position of the grid's inflow boundaries, relative to the primary's position. Thus the injected mass-loss is actually 3x10-4Moyr-1. With this in mind, a Mdotparticle ~ 4x10-6Moyr-1 (green profile) is sensible. I'm running a 10au and a 20au (with more res) versions, with a corrected mass-loss of 10-5Moyr-1. I can already see a lower Mdotparticle for the 10au case.
  • Here's the very preliminary paper's draft. A LOT is needed still, ​http://www.pas.rochester.edu/~martinhe/2011/binary/draft1.pdf
  • Progress in kraken (managed to run for ~8hrs on 4092p), but issues too, see tickets 209 and 217. Will try the latest rev.
  • The code is behaving well in steele, but queues are very, very busy.

Towers. Working on the ApJ referee's comments on the paper.

AGN jet truncation by red giant stellar winds. Latest sim ​http://www.pas.rochester.edu/~martinhe/2011/agn/hd-strongJet-edge2.gif shows that the red giant's (RG) wind, which crosses the edge of the jet's beam, strongly affects the collimation of the AGN jet. Note that in the previous sim (​http://www.pas.rochester.edu/~martinhe/2011/agn-6apr-dens2.gif) the RG's orbital path intersected the jet's axis, affecting the jet's beam more drastically.

Can you convert the gif to an AVI if you have time? FastMovieProcessor on the groups laptop can open a gif and output it as an AVI
