The Challenge of Sub-Keplerian Rotation for Disk Winds
arXiv:0806.2137 · doi:10.1086/591028
Abstract
Strong magnetization makes the disks surrounding young stellar objects rotate at rates that are too sub-Keplerian to enable the thermal launching of disk winds from their surfaces unless the rate of gas diffusion across field lines is dynamically fast. This under-appreciated implication of disk magnetization poses a considerable challenge for disk-wind theory.
