Descripción
The PN M2-48 is formed by three main structures, namely, a bipolar
central region (CR), a set of knots tracing a semicircular shell
surrounding CR, and two symmetric bow-shocks. CR shows a kinematic
structure corresponding to a bipolar shell, with an expansion velocity
of =~ 50kms-1. The semicircular shell appears to be expanding at =~
20kms-1, except in the regions aligned with the bow-shocks, which are
interpreted as jet-shell interaction zones at =~ 100kms-1. Finally, the
bow-shocks have uncorrected velocities of =~ 80kms-1. An inclination
angle of 10^o with respect to the plane of the sky is estimated using
simple bow shock models.
