An extensive numerical survey of the correlation between outflow
  dynamics and accretion disk magnetization
  We investigate the accretion-ejection process of jets from magnetized
accretion disks. We apply a novel approach to the jet-launching problem in
order to obtain correlations between the physical properties of the jet and the
underlying disk. We extend and confirm the previous works of
\citet{2009MNRAS.400..820T} and \citet{2010A&A...512A..82M} by scanning a large
parameter range for the disk magnetization, $\mu_{\rm D} = 10^{-3.5} ...
10^{-0.7}$. We disentangle the disk magnetization at the foot point of the
outflow as the main parameter that governs the properties of the outflow. We
show how the four jet integrals known from steady-state MHD are correlated to
the disk magnetization at the jet foot point. This agrees with the usual
findings of the steady-state theory, however, here we obtain these correlations
from time-dependent simulations that include the dynamical evolution of the
disk in the treatment. In particular, we obtain robust correlations between the
local disk magnetization and (i)the outflow velocity, (ii) the jet mass
loading, (iii) jet angular momentum, and (iv) the local mass accretion rate.
Essentially we find that strongly magnetized disks launch more energetic and
faster jets, and, due to a larger Alfv\'en lever arm, these jets extract more
angular momentum from the underlying disk. These kind of disk-jet systems have,
however, a smaller mass loading parameter and a lower mass
ejection-to-accretion ratio. The jets are launched at the disk surface where
the magnetization is $\mu(r,z) \simeq 0.1$. The magnetization rapidly increases
vertically providing the energy reservoir for subsequent jet acceleration. We
find indication for a critical disk magnetization $\mu_{\rm D} \simeq 0.01$
that separates the regimes of magnetocentrifugally-driven and magnetic
pressure-driven jets.
