Evolved stars: dust formation and mass loss
Luis Velilla-Prieto, Wouter Vlemmings, Guillermo Quintana-Lacaci +18
Evolved stars drive the chemical enrichment of the Universe, acting as primary producers of elemental products of nucleosynthesis and cosmic dust. Unraveling the exact role played…
Evolved stars, multiplicity and planets: Shaping and Being Shaped by Stellar Evolution
Theo Khouri, Wouter Vlemmings, Elvire De Beck +21
Understanding how planets and stellar companions survive and interact with their host stars as they evolve, or are ultimately destroyed in the process, is essential both for predic…
MATISSE unveils a dusty disc in the interior of EP Aquarii. First evidence of a misaligned hierarchical triple system with a central AGB star?
J. Alonso-Hernández, C. Paladini, C. Sánchez Contreras +26
Aims. We have mapped the dust and molecular gas emission distributions in the vicinity (a few stellar radii) of the asymptotic giant branch (AGB) star EP\,Aquarii, with a previousl…
The Molecular Circumstellar Environments of Red Supergiants in Galactic Open Clusters
Mark A. Siebert, Elvire De Beck, Guillermo Quintana-Lacaci +4
We aim to expand the sample of RSGs with direct measurements of circumstellar gas through millimeter observations of two of the largest coeval RSG populations in the Galaxy: the op…
Multiplicity of Cool Stars and their Evolution
Matthew I. Swayne, Leen Decin, Theo Khouri +12
Making up a sizeable portion of the galactic census, stellar multiples are experiencing a renaissance. Enabling the study of multiple strands of the study of cool stars, stellar mu…
Periodic activity on the (sub)mm surface of the AGB star Mira A
M. Andriantsaralaza, B. Bojnordi Arbab, W. Vlemmings +7
Evolved stars on the asymptotic giant branch (AGB) lose mass through stellar winds launched from their dynamic extended atmospheres. Recent high-angular-resolution observations of…
A giant magnetic eruption from the asymptotic giant branch star Mira A
W. Vlemmings, M. Andriantsaralaza, B. Bojnordi Arbab +14
Mass loss during the advanced evolutionary stages of low- and intermediate-mass stars is traditionally attributed to dust-driven winds, whereas the influence of magnetic fields rem…
The unique capabilities of HST for stellar physics: Probing Atmospheric Structure, Chromospheres, and Mass Loss of Evolved Stars
Maryam Saberi, Graham Harper, Jacco Th. van Loon +10
Evolved stars are among the primary sources of chemical enrichment and dust production in galaxies. During the giant phases, stars return a substantial fraction of their mass to th…
HST observations of chromospheric UV lines in the AGB star R Leo
Maryam Saberi, Donald G. Luttermoser, Graham M. Harper +3
The role of stellar chromospheres in the chemistry, mass loss, and evolution of cool evolved stars remains poorly understood. We present high-resolution ultraviolet spectra of the…
OH/IR stars in the inner Galactic bulge: I. Colour, CO line, and stellar light curve characteristics
H. Olofsson, T. Khouri, S. Muller +11
Stars on the asymptotic giant branch (AGB) play important roles in a number of astronomical contexts. To quantify these roles, it is necessary to establish the mass-loss characteri…
A surprisingly large asymmetric ejection from Mira A
T. Khouri, W. H. T. Vlemmings, D. A. Raudales Oseguera +6
Stars with masses between roughly 1 and 8~ end their lives on the asymptotic giant branch (AGB), when intense mass loss takes place. The outflows are generally accepted to…
