H molecular gas in the old planetary nebula NGC 3587
G. Ramos-Larios, M. A. Guerrero, J. A. Toalá +2
The acquisition of high-quality deep images of planetary nebulae (PNe) has allowed the detection of a wealth of small-scale features, which highlight the complexity of the formatio…
Detection of optical emission from the supernova remnant G7.7-3.7
V. Domček, J. V. Hernández Santisteban, A. Chiotellis +6
We present the first optical study of the supernova remnant (SNR) G7.7-3.7, with the aim of determining its evolutionary phase since it has been suggested to be the remnant of SN 3…
Analysis of Integral Field Spectroscopy observations of the planetary nebula Hen 2-108 and its central star
Bárbara L. Miranda Marques, Hektor Monteiro, Isabel Aleman +3
The study of planetary nebulae provides important constraints for many aspects of stellar and Galactic evolution. Hen 2-108 is a poorly known planetary nebula with a slight ellipti…
Planetary nebulae hosting accreting white dwarfs: A possible solution for the mysterious cut-off of Planetary Nebula Luminosity Function?
D. Souropanis, A. Chiotellis, P. Boumis +2
Many binary companions to the central stars of planetary nebulae (PNe) are found to be inflated, perhaps indicating that accretion onto the central star might occur during the PN p…
Where are the missing symbiotic stars? Uncovering hidden Symbiotic Stars in public catalogues
Stavros Akras
Theoretical predictions of the population of Galactic symbiotic stars (SySts) are highly inconsistent with the current known population. Despite intense effort over the past decade…
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…
