HD29:planetary wind and Mass loss

1. Planetary Wind With Temperature Profile

I have been trying to get a high-res picture for planetary wind HD29 with temperature profile. This picture shows there's a shock from the night-side and there's a back-flow.

frame 40
frame 48

The shock disappeared as time goes further, although still need to double-check if this comes form the restarting problem

2. Estimate of the Mass Loss Rate

1). The mass loss rate is estimated by calculating the flux \int \rho V\cdot dS out of the cubic surfaces as show below:

Where the size of box is 0.4*Orbital separation between the star and the planet, or 0.019 AU and the planet is sitting in the center of the box.

2). The mass loss rate for no-temperature-profile case is 3.82E+09 gram per sec, see blog:bliu09222015

3). For with-temperature-profile case, I checked the mass loss rate for different frames

frame	Picture	Mass loss rate
Frame 48		1.33E+09 gram per sec
Frame 70 3AMR		1.55E+09 gram per sec
Frame 76 3AMR		1.56E+09 gram per sec
