[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. Santamaría, 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…
Chemical abundances and ionizing mechanisms in the star-forming double-ring of AM 0644-741 using MUSE data
V. M. A. Gómez-González, Y. D. Mayya, J. Zaragoza-Cardiel +6
We present the analysis of archival Very Large Telescope (VLT) Multi-Unit Spectroscopic Explorer (MUSE) observations of 179 HII regions in the star-forming double-ring collisional…
3D physical structure and angular expansion of the remnant of the recurrent nova T Pyx
E. Santamaría, 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…
