Wind Capture Accretion Disks and Magnetic Towers in pPN
Abstract
We present new results of 3-D AMR MHD simulations focusing on two distinct aspects of pPN evolution. We first report the results of a campaign of simulations to explore the development of accretion disks formed via wind capture. Our result focus on the limits of disk formation and the range of disk properties. We also present new simulations of collimated outflows driven entirely by magnetic fields. These Poynting flux dominated "magnetic towers" hold promise for explaining key properties of pPN flows. Our simulations address magnetic tower evolution and stability.
