Wind-driving protostellar accretion discs - I. Formulation and parameter constraints

Konigl, Arieh; Salmeron, Raquel; Wardle, Mark


We study a model of weakly ionized, protostellar accretion discs that are threaded by a large-scale, ordered magnetic field and power a centrifugally driven wind. We consider the limiting case where the wind is the main repository of the excess disc angular momentum and generalize the radially localized disc model of Wardle & Königl, which focused on the ambipolar diffusion regime, to other field diffusivity regimes, notably Hall and Ohm. We present a general formulation of the problem for...[Show more]
