Analytical solution of magnetically dominated astrophysical jets and winds: jet launching, acceleration, and collimation
We present an analytical solution of a highly magnetized jet/wind flow. The left side of the
general force-free jet/wind equation (the" pulsar" equation) is separated into a rotating and a …
