Abstract
We present a morphokinematic analysis based on high-resolution long-slit echelle spectroscopy of the [N ii] (Formula presented.) line and narrowband imaging. Position–velocity diagrams reveal asymmetric expansion and localized kinematic features. We derive a systemic velocity of (Formula presented.) km s−1 ((Formula presented.) km s−1) and a main shell expansion velocity of (Formula presented.) km s−1. Three-dimensional modeling indicates an ellipsoidal main body surrounded by a thin shell, two ear-like protrusions, and additional small-scale structures. The corresponding kinematic ages are (Formula presented.) yr for the ellipsoid and ring, and (Formula presented.) yr and (Formula presented.) yr for the two opposite ear-like protrusions, respectively, indicating that these outer structures predate the main nebular envelope. The kinematic asymmetry and enhanced emission regions suggest evolution within a non-uniform ambient medium. At the same time, the presence of collimated ear-like structures is consistent with shaping influenced by binary interaction, where earlier outflows preceded the ejection of the dense shell. NGC 6563 therefore appears to be a dynamically evolved system shaped by the combined effects of episodic mass ejection and environmental interaction.
