Technetium-rich M Stars: Prime diagnostics of recent third dredge-up events on the Asymptotic Giant Branch
Shreeya Shetye, Sophie Van Eck, Alain Jorissen +6
Context. Technetium (Tc)-rich M-type stars have been known for over 45 years. However, the origin of Tc in these stars, particularly its detection without the concomitant detection…
The impact of third dredge-up on the mass loss of Mira variables
S. Uttenthaler, S. Shetye, A. Nanni +8
Context: The details of the mass-loss process in the late stages of low- and intermediate-mass stellar evolution are not well understood, in particular its dependence on stellar pa…
Meandering periods and asymmetries in light curves of Miras: Observational evidence for low mass-loss rates
P. Merchan-Benitez, S. Uttenthaler, M. Jurado-Vargas
Some Miras -- long-period variables in late evolutionary stages -- have meandering pulsation periods and light curve asymmetries, the causes of which are still unclear. We aim to u…
The Nearby Evolved Stars Survey II: Constructing a volume-limited sample and first results from the James Clerk Maxwell Telescope
P. Scicluna, F. Kemper, I. McDonald +89
The Nearby Evolved Stars Survey (NESS) is a volume-complete sample of 850 Galactic evolved stars within 3\,kpc at (sub-)mm wavelengths, observed in the CO (21) and…
Interplay between pulsation, mass loss, and third dredge-up: More about Miras with and without technetium
Stefan Uttenthaler, Iain McDonald, Klaus Bernhard +2
We follow-up on a previous finding that AGB Mira variables containing the 3DUP indicator technetium (Tc) in their atmosphere form a different sequence of K-[22] colour as a functio…
A New Sample of Mid-Infrared Bright, Long-Period Mira Variables from the MACHO Galactic Bulge Fields
Klaus Bernhard, Stefan Uttenthaler, Stefan Hümmerich
Mid-infrared bright objects in the direction of the Galactic Bulge were investigated using time series photometry from the MACHO data archive, which led to the discovery of a large…
