【44页精品】Ambipolar Diffusion in Action: Transient C shock Structure and Prestellar Core Formation
Abstract: We analyze the properties of steady and time-dependent C shocks under conditions prevailing in giant molecular clouds. For steady C shocks, we show that ionization equilibrium holds and use numerical integrations to obtain the shock thickness mediated by ambipolar diffusion as a function of density, inflow velocity, magnetic field, and ionization fraction in the cloud. Our formula also agrees with an analytic estimate based on ion-neutral momentum exchange. Using time-dependent numerical simulations, we show that C shocks have a transient stage when the neutrals are compressed much more strongly than the magnetic field. The transient stage has a duration set by the neutral-ion collision time, t_AD ~ L_shock/v_drift ~ 0.1 - 1 Myr. This transient creates a strong enhancement in the mass-to-magnetic flux ratio. Under favorable conditions, supercritical prestellar cores may form and collapse promptly as a result of magnetic flux loss during the transient stage of C shocks..

Dynamics of fluctuating magnetic fields in turbulent dynamos incorporating ambipolar drifts
Turbulence with a large magnetic Reyonolds number, generically leads to nrapidly growing magnetic noise over and above any mean field. We revisit the ndynamics of this fluctuating field, in homogeneous, isotropic, helical nturbulence. Assuming the turbulence to be Markovian, we first rederive, in a nfairly transparent manner, the equation for the mean field, and corrected nFokker-Plank type....
