The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
Orsola De Marco, Muhammad Akashi, Stavros Akras +66
Planetary nebulae (PNe), the ejected envelopes of red giant stars, provide us with a history of the last, mass-losing phases of 90 percent of stars initially more massive than the…
The miniJPAS survey: stellar atmospheric parameters from 56 optical filters
H. -B. Yuan, L. Yang, P. Cruz +29
With a unique set of 54 overlapping narrow-band and two broader filters covering the entire optical range, the incoming Javalambre-Physics of the Accelerating Universe Astrophysica…
Low-ionization structures in planetary nebulae -- II. Densities, temperatures, abundances and excitation of 6 PNe
M. Belén Mari, Denise R. Gonçalves, Stavros Akras
Here we present the spatially resolved study of six Galactic planetary nebulae (PNe), namely IC 4593, Hen 2-186, Hen 2-429, NGC 3918, NGC 6543 and NGC 6905, from intermediate-resol…
Spectroscopic Analysis Tool for intEgraL fieLd unIt daTacubEs (satellite): Case studies of NGC 7009 and NGC 6778 with MUSE
S. Akras, H. Monteiro, J. R. Walsh +11
Integral field spectroscopy (IFS) provides a unique capability to spectroscopically study extended sources over a 2D field of view, but it also requires new techniques and tools. I…
Discovery of five new Galactic symbiotic stars in the VPHAS+ survey
Stavros Akras, Denise R. Gonçalves, Alvaro Alvarez-Candal +1
We report the validation of a recently proposed infrared selection criterion for symbiotic stars (SySts). Spectroscopic data were obtained for seven candidates, selected from the S…
The miniJPAS survey: a preview of the Universe in 56 colours
S. Bonoli, A. Marín-Franch, J. Varela +166
The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will soon start to scan thousands of square degrees of the northern extragalactic sky with a unique…
