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 Gaia-ESO Survey: Lithium measurements and new curves of growth
E. Franciosini, S. Randich, P. de Laverny +37
The Gaia-ESO Survey (GES) is a large public spectroscopic survey that was carried out using the multi-object FLAMES spectrograph at the Very Large Telescope. The survey provides ac…
The Gaia-ESO Public Spectroscopic Survey: Motivation, implementation, GIRAFFE data processing, analysis, and final data products
G. Gilmore, S. Randich, C. C. Worley +165
The Gaia-ESO Public Spectroscopic Survey is an ambitious project designed to obtain astrophysical parameters and elemental abundances for 100,000 stars, including large representat…
Sr and Ba abundance determinations: comparing machine-learning with star-by-star analyses -- High-resolution re-analysis of suspected LAMOST barium stars
D. Karinkuzhi, S. Van Eck, A. Jorissen +6
A new large sample of 895 s-process-rich candidates out of 454180 giant stars surveyed by LAMOST at low spectral resolution (R ~ 1800) has been reported by Norfolk et al. (2019; he…
Low-mass low-metallicity AGB stars as an efficient i-process site explaining CEMP-rs stars
D. Karinkuzhi, S. Van Eck, S. Goriely +5
Among Carbon-Enhanced Metal-Poor (CEMP) stars, some are found to be enriched in s-process elements (CEMP-s), in r-process elements (CEMP-r) or in both s- and r-process elements (CE…
Discovery of technetium- and niobium-rich S stars: the case for bitrinsic stars
S. Shetye, S. Van Eck, S. Goriely +4
S stars are late-type giants with overabundances of s-process elements. They come in two flavours depending on the presence or not of technetium (Tc), an element without stable iso…
