A spectroscopic quadruple as a possible progenitor of sub-Chandrasekhar Type Ia supernovae
T. Merle, A. S. Hamers, S. Van Eck +13
Binaries have received much attention as possible progenitors of Type Ia supernova (SNIa) explosions, but long-term gravitational effects in tight triple or quadruple systems could…
The Mg-K anti-correlation in Omega Centauri
Deimer Antonio Alvarez Garay, Alessio Mucciarelli, Carmela Lardo +2
We present [K/Fe] abundance ratios for a sample of 450 stars in Omega Centauri, using high resolution spectra acquired with the multi-object spectrograph FLAMES@VLT. Abundances for…
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…
Atmosphere of Betelgeuse before and during the Great Dimming event revealed by tomography
K. Kravchenko, A. Jorissen, S. Van Eck +7
Despite being the best studied red supergiant star in our Galaxy, the physics behind the photometric variability and mass loss of Betelgeuse is poorly understood. Moreover, recentl…
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…
The GALAH survey: Multiple stars and our Galaxy. I. A comprehensive method for deriving properties of FGK binary stars
G. Traven, S. Feltzing, T. Merle +24
Binary stellar systems form a large fraction of the Galaxy's stars. They are useful as laboratories for studying the physical processes taking place within stars, and must be corre…
