Query: Self-Similar Solution of Hot Accretion Flows with Ordered Magnetic Field
  and Outflow   Observations and numerical magnetohydrodynamic (MHD) simulations indicate the
existence of outflows and ordered large-scale magnetic fields in the inner
region of hot accretion flows. In this paper we present the self-similar
solutions for advection-dominated accretion flows (ADAFs) with outflows and
ordered magnetic fields. Stimulated by numerical simulations, we assume that
the magnetic field has a strong toroidal component and a vertical component in
addition to a stochastic component. We obtain the self-similar solutions to the
equations describing the magnetized ADAFs, taking into account the dynamical
effects of the outflow. We compare the results with the canonical ADAFs and
find that the dynamical properties of ADAFs such as radial velocity, angular
velocity and temperature can be significantly changed in the presence of
ordered magnetic fields and outflows. The stronger the magnetic field is, the
lower the temperature of the accretion flow will be, and the faster the flow
rotates. The relevance to observations is briefly discussed.
