Query: Jet magnetically accelerated from disk-corona around a rotating black
  hole   A jet acceleration model for extracting energy from disk-corona surrounding a
rotating black hole is proposed. In the disk-corona scenario, we obtain the
ratio of the power dissipated in the corona to the total for such disk-corona
system by solving the disk dynamics equations. The analytical expression of the
jet power is derived based on the electronic circuit theory of the
magnetosphere. It is shown that jet power increases with the increasing black
hole (BH) spin, and concentrates in the inner region of the disk-corona. In
addition, we use a sample consisting of 37 radio loud quasars to explore their
jet production mechanism, and show that our jet formation mechanism can
simulate almost all sources with high power jet, that fail to be explained by
the Blandford-Znajek (BZ) process.
