Modeling the magnetized accretion and outflows in young stellar objects

Recent results of magnetohydrodynamic (MHD) simulations are presented treating the launching of jets from young stellar object accretion disks. The simulations consider the evolution of magnetically diffusive disks that eject high-speed outflows. A few exemplary results are presented: (i) the disk structural evolution that leads to different launching conditions over time, (ii) a general interrelation between the disk magnetization at the outflow launching radius and the outflow asymptotic properties, (iii) jet launching within a self-generated disk magnetic field amplified by a disk mean field dynamo, and (iv) simulations of jets from orbiting jet sources
