Martin's update, 13 mar '12

Binary.

I'm continuing working on the 40AU case. High res sims have produced a "disk-like" structure, the angular momentum vector of which seems to point towards the primary. It doesn't make sense to me. I'm investigating this but suspect it may be related to the fact that the secondary pulls before the it is inside the wind (I used this setup for it worked well for our previous runs with Bondi accretion and smaller separations). I want to restart the sim (i) once the secondary is inside the wind (ii) with a secondary which starts pulling gas after restart. The restart procedure has changed in the latest code revisions, so I'm updating my module. IMAGE: 2d density maps showing a part of the orbital plane close to the secondary. Left: rsoft=0; Right: rsoft=dx. Times are different in each panel. http://www.pas.rochester.edu/~martinhe/2011/binary/13mara.png

CRL618.

The tracer field that represents the DM cooling seems to be working well. This sim ran 40% and is scheduled to restart in bgenen soon. http://www.pas.rochester.edu/~martinhe/2011/crl/13mara.png
As discussed last time, I increased the densities of both the clump and the ambient medium by a factor of 10 in order to get stronger cooling and thus thinner lobes. In addition, the AGB wind is toroidal. Here's and image from the low res test, the high res one should run soon. http://www.pas.rochester.edu/~martinhe/2011/crl/13marb.png

PN paper. I've heard back from MNRAS: "…Minor revision of your manuscript is requested before it is reconsidered for publication." :)

Magnetic tower. Waiting for comments from Adam, Eric and Pat to submit. I had a discussion with Manoj and he's very interested in out magnetic towers to model some of their recent Hershel observations. He scheduled a talk for me and will ask Adam to give one, in a meeting that he, Dan and other people will have in Rochester in about 3 weeks.

AGN jet truncation. As I said last time, the RG wind looks strange for it is subsonic. New runs:

  1. smaller grid and jet radius by a factor of 2 + more refinement levels,
  2. same as 1 but for a jet kinetic luminosity of 1045ers/s (instead of 4x1042),
  3. same as 1 and 2 but for a magnetized jet. Should have an effect on the RG wind.
