Protoplanetary Disk Size under Nonideal Magnetohydrodynamics: A General Formalism with Inclined Magnetic Field

Blog Article

Many mechanisms have been proposed to alleviate the magnetic catastrophe, which prevents the Keplerian disk from forming inside a collapsing magnetized core.Such propositions include inclined field and nonideal read more magnetohydrodynamics effects, and have been supported with numerical experiments.Models have been formulated for typical disk sizes when a field threads the rotating disk, parallel to the rotation axis, while observations at the core scales do not seem to show evident correlation between the directions of angular momentum and the magnetic field.In the present citronella horse shampoo study, we propose a new model that considers both vertical and horizontal fields and discuss their effects on the protoplanetary disk size.
