Question

Astrophysics question:

A typical T-Tauri star has stellar wind moving at speed and a mass loss rate of $\dot{M}$.

a) Show that the momentum lost per second by the wind is given by .

b) The winds sweep out surrounding dust until, by conservation of momentum, it slows to speed (1/10)v. Show that the rate at which the dust can be driven away is given by:

$\dot{M}_{d}=9\dot{M}$

= Mu
