Title: Planetary Nebula NGC 2818: 3D morphology and new detected structures
Abstract:
Planetary Nebulae (PNe) of highly complicated morphology denote a very active evolutionary history during
the transition from a spherically symmetric AGB envelope to the Planetary Nebula formation. In this category
belongs the bipolar PN NGC 2818, which is accompanied by fragmentations, a bulk of cometary knots and
complex filamentary structures. In this talk I present the results of the 3D Morpho-kinematic (MK) modeling
of NGC 2818. For its reconstruction, long-slit echelle spectra were employed in conjunction with Fabry-Perot
imaging spectroscopy for the first time in a PN project. The interpretation of the outcomes shed light on the
physical mechanisms that created this PN, while new structures of the nebula that come to light for the first time
are also discussed.
