COMMON ENVELOPE SIMULATIONS

New Work

  1. 2D movies for force paper for fiducial run 143 (q=0.5), using de-resolved data.
  2. 1D plots for force paper for runs 143 (q=0.5), 149 (q=0.25) and run 151 (q=0.125), using original data (not de-resolved data).
  3. Redoing force post-processing using reservation on bluehive (pp seems to be more stable with a reservation, but results should hardly change, if at all).
  4. Deleted most of AGB run from bluehive, keeping only 1/5 of frames, to save space (the other frames are still available for now on stampede scratch, but I may move them to backup drive).
  5. Analysis: begun comparison with ​Macleod+17b

Movies

all movies are in the corotating (with the particle orbit) reference frame of particle 2, and particle 2 is at center of the frame, while particle 1 is situated on the axis); movies use de-resolved data

Particularly interesting movies are highlighted in bold font

​Force per unit volume along phi direction

Force per unit volume between particle 2 and gas along direction of particle 2 velocity relative to particle 1 (magnitude), with contours also showing the same quantity plotted in color with contour values equal to values labeled on the color bar, and with vectors on particle 2 showing velocity of particle 2 relative to particle 1, and on particles 1 and 2 showing net force on each particle exerted by the gas, slice through orbital plane (view size ):

Next steps

  • Understanding 1D plots in terms of 2D movies (in progress, for discussion at meeting)
  • Comparison with ​MacLeod+17b (in progress, for discussion at meeting)
  • Comparison with ​Rheichardt+19 (in progress, for discussion at meeting)
  • Comparison with ​Ricker+Taam12 (in progress, for discussion at meeting)
  • Understand better the BHL theory/Dodd+McCrea theory and adjust analytic formulae if necessary, also estimate factor.
  • Redo movies using full resolution data (after deciding which ones are most important)
  • Movies for runs 149 and 151
  • Post-processing of simulations to extract forces: I'm re-doing it with a reservation on bluehive to ensure that the results are correct as there had been some issues when I had done this the first time without a reservation (in progress)
  • Movies and analysis for run 132 (subgrid accretion run) (partly complete)
  • Calculate force from loss of angular momentum
