Nickel- and iron-rich clumps in planetary nebulae: New discoveries and emission-line diagnostics
K. Bouvis, S. Akras, H. Monteiro +7
Integral field spectroscopy (IFS) offers a distinct advantage for studying extended sources by enabling spatially resolved emission maps for several emission lines without the need…
The planetary nebula NGC 3132 revisited: high definition 3D photoionization model
H. Monteiro, C. Mendes de Oliveira, P. Amram +6
We present a detailed 3D photoionization model of the planetary nebula NGC 3132, constrained by the latest observations. Using the MOCASSIN code, the model incorporates integrated…
Integral field spectroscopy of the planetary nebula NGC 3242 and the puzzling nature of its low ionization structures
L. Konstantinou, S. Akras, J. Garcia-Rojas +7
The physico-chemical properties of the planetary nebula (PN) NGC 3242 are investigated in both 1D and 2D, using Integral Field Unit (IFU) data. This PN has a complex morphology wit…
[Fe II] 1.644m imaging survey of planetary nebulae with low-ionisation structures
Stavros Akras, Isabel Aleman, Denise R. Gonçalves +2
Low-ionisation structures (LISs) are commonly found in planetary nebulae (PNe) but they are still poorly understood. The recent discovery of unforeseen molecular hydrogen gas (H2)…
