Proper motion of the central star of the Planetary Nebula Sh 2-68.

Abstract (from CDS):

We report on the discovery of the proper motion of the central star (CS) of the Planetary Nebula (PN) Sh2-68 (PN G030.6+06.2). Sh2-68 is a PN interacting with the interstellar medium (ISM), which impedes and finally stops the expansion of the nebula itself while the galactic motion of the CS leads to it moving out of the geometric center of the PN. Our observation is a direct confirmation of this process and combined with imaging data suggests that the ISM's magnetic field plays an important role in shaping and destroying evolved PNe. The proper motion of 53.2±5.5mas/yr is the largest value for a PN found from ground based observations.
