Morphokinematic structure of the Planetary Nebula NGC 6563
Zahra Al, Federico Soto-Badilla, Yüksel KarataŠ+2
We present a morphokinematic analysis based on high-resolution long-slit echelle spectroscopy of the \nii line and narrowband imaging. Position-velocity diagrams revea…
A morphological catalogue of Nova Remnants
Edgar Santamaria, Martin A. Guerrero, Gerardo Ramos-Larios +2
This work presents the first optical imaging catalogue of resolved Galactic nova remnants. It compiles images from proprietary observations carried out at the Nordic Optical Telesc…
[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)…
Identification of planetary and proto-planetary nebulae candidates through akari infrared photometry
R. A. Marquez-Lugo, S. N. Kemp, G. Ramos-Larios +3
We utilized photometric data from the space telescope AKARI to identify potential planetary nebulae (PNe) and proto-planetary nebulae (PPNe) candidates. Using the colour-colour dia…
Shaping the nebula around the symbiotic system R Aquarii
E. SantamarÃa, J. A. Toalá, T. Liimets +4
We present an analysis of high-dispersion spectroscopic observations of the symbiotic system R Aquarii (R Aqr) obtained with the Manchester Echelle Spectrograph (MES) at the 2.1 m…
3D physical structure and angular expansion of the remnant of the recurrent nova T Pyx
E. SantamarÃa, J. A. Toalá, M. A. Guerrero +2
We present the analysis of archival Very Large Telescope (VLT) MUSE and multi-epoch Hubble Space Telescope (HST) WFPC2 and WFC3/UVIS narrow-band observations of the remnant associa…
