Gravitational Instabilities In A Protoplanetary Disk Including The Effects Of Magnetic-Fields [PDF]

open access: yes, 1994
We investigate the gravitational instability of a thin, Keplerian protoplanetary disk including the effects of a largely azimuthal magnetic field. The model follows that of our previous work (Noh, Vishniac, & Cochran 1991) except for the inclusion of a ...
