A 0.1339 solar mass object is located at origin and emitting wind. Although parameters change in the following simulations, the functional form of time dependent variables behave alike.

The initial velocity of the wind and The density of the wind vary as:

Red line indicate the escape velocity at the radius where the wind is launched.

Conclusions:

1. Fall back radius is sensitive to the value of post pulse wind momentum.

2. I guess the time of fractal of dense shell is relevant to the duration of pulsation (given the same other conditions).
