Query: Magnetic Reconnection under Anisotropic MHD Approximation   We study the formation of slow-mode shocks in collisionless magnetic
reconnection by using one- and two-dimensional collisionless MHD codes based on
the double adiabatic approximation and the Landau closure model. We bridge the
gap between the Petschek-type MHD reconnection model accompanied by a pair of
slow shocks and the observational evidence of the rare occasion of in-situ slow
shock observation. Our results showed that once magnetic reconnection takes
place, a firehose-sense pressure anisotropy arises in the downstream region,
and the generated slow shocks are quite weak comparing with those in an
isotropic MHD. In spite of the weakness of the shocks, however, the resultant
reconnection rate is 10-30% higher than that in an isotropic case. This result
implies that the slow shock does not necessarily play an important role in the
energy conversion in the reconnection system, and is consistent with the
satellite observation in the Earth's magnetosphere.
