Fluorine in the Solar neighborhood: No evidence for the neutrino process
H. Jönsson, N. Ryde, E. Spitoni +5
Asymptotic Giant Branch stars are known to produce `cosmic' fluorine but it is uncertain whether these stars are the main producers of fluorine in the Solar neighborhood or if any…
Non-local thermodynamic equilibrium stellar spectroscopy with 1D and 3D models - II. Chemical properties of the Galactic metal-poor disc and the halo
Maria Bergemann, Remo Collet, Ralph Schoenrich +5
From exploratory studies and theoretical expectations it is known that simplifying approximations in spectroscopic analysis (LTE, 1D) lead to systematic biases of stellar parameter…
Non-local thermodynamic equilibrium stellar spectroscopy with 1D and <3D> models - I. Methods and application to magnesium abundances in standard stars
Maria Bergemann, Remo Collet, Anish M. Amarsi +3
We determine Mg abundances in 6 Gaia benchmark stars using theoretical one-dimensional (1D) hydrostatic model atmospheres, as well as temporally- and spatially-averaged 3D model at…
The Gaia-ESO Survey: calibration strategy
E. Pancino, the Gaia-ESO Survey collaboration
The Gaia-ESO survey (GES) is now in its fifth and last year of observations, and has already produced tens of thousands of high-quality spectra of stars in all Milky Way components…
Exocomet signatures around the A-shell star Leo?
C. Eiroa, I. Rebollido, B. Montesinos +18
We present an intensive monitoring of high-resolution spectra of the Ca {\sc ii} K line in the A7IV shell star Leo at very short (minutes, hours), short (night to night), and m…
CRIRES-POP: a library of high resolution spectra from 1 to 5 microns II. Data reduction and the spectrum of the K giant 10 Leo
C. P. Nicholls, T. Lebzelter, A. Smette +12
Context. High resolution stellar spectral atlases are valuable resources to astronomy. They are rare in the m region for historical reasons, but once available, high reso…
