Evolutionary versus dynamical time scales for the evolution of the central stars of planetary nebulae
The disagreement between evolutionary and dynamical time scales for the evolution of the central stars of planetary nebulae (CSPN) through the H-R diagram is...
Evolved stars in the Local Group galaxies - I. AGB evolution and dust production in IC 1613
We used models of thermally pulsing asymptotic giant branch (AGB) stars, which also describe the dust-formation process in the wind, to interpret the...
Evolved stars in the Local Group galaxies - II. AGB, RSG stars, and dust production in IC10
We study the evolved stellar population of the Local Group galaxy IC10, with the aim of characterizing the individual sources observed and to derive global...
Evolved stars in the Local Group galaxies - III. AGB and RSG stars in Sextans A
We study the evolved stellar population of the galaxy Sextans A. This galaxy is one of the lowest metallicity dwarfs in which variable asymptotic giant branch...
Evolved stars suggest an external origin of the enhanced metallicity in planet-hosting stars
Aims: Exo-planets are preferentially found around high metallicity main sequence stars. We investigate whether evolved stars share this property, and its...
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Westerlund 1 and 2 Open Clusters Survey
Context. With a mass exceeding several 10 4 M ⊙ and a rich and dense population of massive stars, supermassive young star clusters represent the most massive...
EX draconis: using eclipses to separate outside-in and inside-out outbursts
We present a study of the eclipses in the accreting white dwarf EX draconis (EX Dra) during TESS Cycles 14 and 15. During both of the two outbursts present in...
Aims: EX Lupi is the prototype of EXors, a subclass of low-mass pre-main sequence stars whose episodic eruptions are attributed to temporarily increased...
