The Morphology and Kinematics of the Complex Polypolar Planetary Nebula NGC 2440

Abstract

Spatially resolved proles of the Ha, [N II] 6584 and [O III] 5007 lines have been obtained with A , A the Manchester echelle spectrometer combined with the 2.1 m San Pedro Ma rtir telescope over the planetary nebula NGC 2440. The resulting position-velocity (PV) arrays are compared with ground-based and HST archival imagery, revealing the complex structure that prevails in this object. This work represents the rst detailed kinematical study of NGC 2440.
