  • Disk formation in binaries. The shape of the stagnation point. Images from the 15AU case. CLICK TO ENLARGE.
Vel. streamlines that start close to the grid boundaries and finish (most of them) in the disk. Black is fast and white is slow.Pole-on view http://www.pas.rochester.edu/~martinhe/16octa.pngPerspective view http://www.pas.rochester.edu/~martinhe/16octb.png
Iso-surfaces. Blue=disk; red=low vel gas.http://www.pas.rochester.edu/~martinhe/16octc.png
One white vel streamline that starts at the boundary, gets to the stagnation point and is accreted then. Velocity field in colors in the vicinities of the stagnation region.http://www.pas.rochester.edu/~martinhe/16octd.png

My conclusion form these plots is that the stagnation occurs at a surface with a complex shape; not a point. Lets call this the stagnation region. An improved version of these images has been added to the paper.

  • Poloidal collimation of isotropic winds. Phone call with Andrea. He has new unpublished experimental data in magnetic field strengths never explores before. He has simulations of the experiments which agree quite well. Wants me to find astro parameters which will match the morphology and shock structure they see. Also, to connect the experiments and their sim, with our astro sims and thus astro observations.

Can you make contour where |v| ~ 0?

And maybe rotate these to get some perspective?

Jonathan: The red contours in the second row (above) are for |v|~0. I've tried playing with view points to get a better idea, but these seemed the best ones. I could give you some of the data if u want to try.
