Query: Effects of anisotropic thermal conduction on wind properties in hot
  accretion flow   Previous works have clearly shown the existence of winds from black hole hot
accretion flow and investigated their detailed properties. In extremely low
accretion rate systems, the collisional mean-free path of electrons is large
compared with the length-scale of the system, thus thermal conduction is
dynamically important. When the magnetic field is present, the thermal
conduction is anisotropic and energy transport is along magnetic field lines.
In this paper, we study the effects of anisotropic thermal conduction on the
wind production in hot accretion flows by performing two-dimensional
magnetohydrodynamic simulations. We find that thermal conduction has only
moderate effects on the mass flux of wind. But the energy flux of wind can be
increased by a factor of $\sim 10$ due to the increase of wind velocity when
thermal conduction is included. The increase of wind velocity is because of the
increase of driving forces (e.g. gas pressure gradient force and centrifugal
force) when thermal conduction is included. This result demonstrates that
thermal conduction plays an important role in determining the properties of
wind.
