Planetary Nebula NGC 2818: Revealing its complex 3D morphology
Sophia Derlopa, Stavros Akras, Philippe Amram +3
We carry out an advanced morpho-kinematic analysis of the Planetary Nebula (PN) NGC 2818, whose complex morphology is described by a basic bipolar component, filamentary structures…
Discovery of an optical cocoon tail behind the runaway HD 185806
Z. T. Spetsieri, P. Boumis, A. Chiotellis +6
Studies on the circumstellar structures around evolved stars provide vital information on the evolution of the parent star and the properties of the local interstellar medium. In t…
Two New Nova Shells associated with V4362 Sagittarii and DO Aquilae
E. J. Harvey, M. P. Redman, P. Boumis +8
A classical nova is an eruption on the surface of a white dwarf in an accreting binary system. The material ejected from the white dwarf surface generally forms an axisymmetric she…
The first 3D Morpho-kinematical model of a Supernova Remnant: The case of VRO 42.05.01 (G 166.0+4.3)
Sophia Derlopa, Panos Boumis, Alexandros Chiotellis +2
We present the preliminary results of the first 3-dimensional (3D) Morpho-Kinematical (MK) model of a supernova remnant (SNR), using as a study case the Galactic SNR VRO 42.05.01 (…
High velocity string of knots in the outburst of the Planetary Nebula Hb4
Sophia Derlopa, Stavros Akras, Panos Boumis +1
The bipolar collimated outflows of the Hb4 Planetary Nebula (PN) exhibit an evident decrease in their expansion velocity with respect to the distance from the central star. So far,…
