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…
Discovery of an optical cocoon tail behind the runaway HD 185806
Z. T. Spetsieri, P. Boumis, A. Chiotellis +6
Studies on the circumstellar structures around evolved stars provide vital information on the evolution of the parent star and the properties of the local interstellar medium. In t…
Multi-band polarimetry of post-asymptotic giant branch stars stars. Optical measurements
S. Akras, J. C. Ramirez Velez, N. Nanouris +4
We present new optical broad-band (UBVRI) aperture polarimetric observations of 53 post-asymptotic giant branch (AGB) stars selected to exhibit a large near-infrared excess. 24 out…
