X-Shooter view of planetary nebulae microstructures I: The case of NGC 7009 knots
L. Konstantinou, S. Akras, K. Bouvis +4
The properties of NGC 7009 knots are investigated by employing UV-to-near-infrared data from the X-Shooter spectrograph. These structures belong to the category of low-ionization s…
NELIOTA Lunar Impact Flash Detection and Event Validation
Alexios Liakos, Alceste Bonanos, Emmanouil Xilouris +9
NELIOTA (NEO Lunar Impacts and Optical TrAnsients) is an ESA-funded lunar monitoring project, which aims to determine the size-frequency distribution of small Near-Earth Objects (N…
The bow-shock and high-speed jet in the faint, 40 arcmin diameter, outer halo of the evolved Helix planetary nebula (NGC 7293)
John Meaburn, Panos Boumis, Stavros Akras
In previous, very deep, optical images of NGC 7293 both a feature that has the morphology of a bow-shock and one with that of a jet were discovered in the faint 40 arcmin diameter…
The expansion proper motions of the extraordinary giant lobes of the planetary nebula KjPn 8 revisited
Panos Boumis, John Meaburn
The primary aim is to establish a firm value for the distance to the extraordinary planetary nebula KjPn 8. Secondary aims are to measure the ages of the three giant lobes of this…
Towards an explanation for the 30 Dor (LMC) Honeycomb nebula - the impact of recent observations and spectral analysis
John Meaburn, Matt P. Redman, Panos Boumis +1
The unique Honeycomb nebula, most likely a peculiar supernova remnant, lies in 30 Doradus in the Large Magellanic Cloud. Due to its proximity to SN1987A, it has been serendipitousl…
Flows along cometary tails in the Helix planetary nebula NGC 7293
John Meaburn, Panos Boumis
Previous velocity images which reveal flows of ionized gas along the most prominent cometary tail (from Knot 38) in the Helix planetary nebula are compared with that taken at optic…
