Observational mapping of the mass discrepancy in eclipsing binaries: Selection of the sample and its photometric and spectroscopic properties
A. Tkachenko, K. Pavlovski, N. Serebriakova +4
Abridged. Eclipsing spectroscopic double-lined binaries are the prime source of precise and accurate measurements of masses and radii of stars. These measurements provide a stringe…
MELCHIORS: The Mercator Library of High Resolution Stellar Spectroscopy
P. Royer, T. Merle, K. Dsilva +71
Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a given object or a given spec…
The ESO UVES/FEROS Large Programs of TESS OB pulsators. I. Global stellar parameters from high-resolution spectroscopy
Nadya Serebriakova, Andrew Tkachenko, Sarah Gebruers +7
Modern stellar structure and evolution theory experiences a lack of observational calibrations for the interior physics of intermediate- and high-mass stars. This leads to discrepa…
Test of binary spectral model on FEROS spectra. First estimation of the fundamental parameters for HD 20784
Mikhail Kovalev, Sarah Gebruers, Ilya Straumit
We analyse spectra of 26 early-type stars, with suspected binarity, using a binary spectral model adapted for high-resolution FEROS spectra. We confirm seven SB2 candidates (AE Pic…
Analysis of high-resolution FEROS spectroscopy for a sample of variable B-type stars assembled from TESS photometry
Sarah Gebruers, Andrew Tkachenko, Dominic M. Bowman +8
Spectroscopic data are necessary to break degeneracies in asteroseismic modelling of the interior structure in high- and intermediate-mass stars. We derive precise photospheric ste…
Zeta-Payne: a fully automated spectrum analysis algorithm for the Milky Way Mapper program of the SDSS-V survey
Ilya Straumit, Andrew Tkachenko, Sarah Gebruers +13
The Sloan Digital Sky Survey has recently initiated its 5th survey generation (SDSS-V), with a central focus on stellar spectroscopy. In particular, SDSS-V Milky Way Mapper program…
Dynamical parallax, physical parameters and evolutionary status of the components of the bright eclipsing binary α Draconis
K. Pavlovski, C. A. Hummel, A. Tkachenko +13
Altough both components of the bright eclipsing binary Dra having been resolved using long baseline interferometry and the secondary component shown to contribute some 15\% of…
Stellar labels for hot stars from low-resolution spectra - I. the HotPayne method and results for 330,000 stars from LAMOST DR6
Maosheng Xiang, Hans-Walter Rix, Yuan-Sen Ting +9
We set out to determine stellar labels from low-resolution survey spectra of hot, OBA stars with effective temperature (Teff) higher than 7500K. This fills a gap in the scientific…
Internal mixing of rotating stars inferred from dipole gravity modes
May G. Pedersen, Conny Aerts, Péter I. Pápics +7
During most of their life, stars fuse hydrogen into helium in their cores. The mixing of chemical elements in the radiative envelope of stars with a convective core is able to repl…
A homogeneous spectroscopic analysis of a Kepler legacy sample of dwarfs for gravity-mode asteroseismology
Sarah Gebruers, Ilya Straumit, Andrew Tkachenko +12
Asteroseismic modelling of the internal structure of main-sequence stars born with a convective core has so far been based on homogeneous analyses of space photometric Kepler light…
Asteroseismic modeling of gravity modes in slowly rotating A/F stars with radiative levitation
Joey S. G. Mombarg, Aaron Dotter, Timothy Van Reeth +3
It has been known for several decades that transport of chemical elements is induced by the process of microscopic atomic diffusion. Yet, the effect of atomic diffusion, including…
