Adjusting the bow-tie: a morpho-kinematic study of NGC 40

We present a comprehensive study of the ionization structure and kinematics planetary nebula (PN) NGC40 (a.k.a. Bow-tie Nebula). A set narrow-band images obtained with ALhambra Faint Object Spectrograph Camera (ALFOSC) at Nordic Optical Telescope (NOT) are used to turbulent distribution gas in main cavity, stratification density this PN. High-resolution Manchester Echelle (MES) observations 2.1m telescope San Pedro M\'{a}rtir (SPM) Observatory unveil great detail kinematic signatures all morphological features NGC40. The spectra suggest that had multiple mass ejections its recent formation history. found 4 jet-like not aligned axis (PA=20$^{\circ}$), some them having pierced cavity along SW-NE direction as well southern lobe. Using tailor-made morpho-kinematic model produced SHAPE we has age 6,500 yr two pairs lobes expanding towards N S directions have an averaged 4,100$\pm$550 yr. thus adds group PNe different axes challenge models PN formation.
