Post Common Envelope Outflows

I put a 1 solar mass object at the origin of the simulation box. There is no outflow from 0 to 6000 day. I list the physical quantities during the quiet phase below:

Radius of the object that has outflow: r=46.875R_{\odot}

Mass of the object: 1M_{\odot}

Density of the outflow: \rho=10^{-13}g\cdot cm^{-3}

Temperature of the object: T_{1}=30000K

After the quiet phase, there is an outflow. An important constraint is the momentum budget. It is related to the luminosity of the object by: \dot{p}\le\frac{L}{c}. Model ID 6 is the old simulation with only 500 days of quite phase.

ID	v_{r}(0)(km\cdot s^{-1})	\rho (g\cdot cm^{-3})	\dot{M}(M_{\odot}\cdot yr^{-1})	\dot{p}c (L_{\odot})	simulation	approximate expansion velocity
6	300 (spherical)	10^{-11}	6.35\times10^{-4}	10^{7}	movies:density
7	300 (spherical)	5\times10^{-13}	3.175\times10^{-5}	5\times10^{5}	movies:density

I think the implied luminosity is still too high for the outflow. Also, it remains a question that what kind of driving mechanism is this outflow? Model 7 seems to be a nova outburst and model 6 seems to be a supernova….
