Meeting Update 07/23/2013 - Dan
I've been trying to fix the problem of my star not being in hydro static equilibrium. I tried the HydroStaticStar module in the latest AstroBEAR and it worked until I tried adding a sink particle.
No Sink Particle | Sink Particle |
---|---|
Martin's code ran on bluehive and needed more time so it's now running with more time. I've also started writing reports for the REU program.

Meeting Update 07/08/2013
Did some runs of the HS disk with a de-resolved center. The red line is the accretion rate for the disk in HS equilibrium with an ambient. The other lines are the accretion rates but when the density of the ambient is an order of magnitude less then the previous line. The red curve has an accretion rate of about .0019 solar masses/yr and the green one has .00748 solar masses/yr, both of these are taken from the 40th cycle and onward.
There are also a few videos (mpeg) attached showing the density and radial flux during a run.
I've also did a small run with the wind driven disk on bluehive, but need to increase the bounds of it to be able to see anything.

Late Meeting Update 7/1/13
Here is some old and new stuff I've been meaning to put up.
Sorry about the size of these. I couldn't get them to shrink. These images show the velocity vectors for a disk in HSE.
I've also attached a few movies of the flow over 10 rotations of the disk.

Meeting Update 6/24
- Had some problems trying use an old module of Martin's (need to get the version of astrobear he used)
- read some papers on post agb-binary stars
- still having problems displaying my data correctly in visit

Meeting update - 6/17/13
- Calculated accretion rates for runs (non HS, seem high)
- figured out a second way to calculate accretion rates
- ran sims for HS equilibrium (still seem high)
- problem running HS sims with too low of an ambient density ("requesting restart due to nan in flux", says it would take 2.8 years)
- need to work on wind capture disk simulations

Meeting Update 6/10/2013
- read review on planetary nebulae
- read paper on wind-capture discs in binary systems
- read over fortran basics
- ran simulations with varying ambient densities (1e-10 to 1e0)
- need to calculate accretion rate of simulations (need to find out how to get mass of point particle at the center of the disk)
