Gaia FGK benchmark stars: Abundances of n-capture elements of the third version
S. Vitali, P. Jofré, L. Casamiquela +10
In the current era, in which an unprecedented wealth of data are available for the study of the Milky Way, Gaia benchmark stars (GBSs) have become an established reference and cali…
Gaia FGK Benchmark Stars: Impact of Spectral Resolution on Stellar Abundances
Ivanna Hernández-Araya, Claudia Aguilera-Gómez, Paula Jofré +5
In the era of large Milky Way spectroscopic surveys, calibrating and standardizing stellar parameters and abundance measurements is crucial. The Gaia benchmark stars (GBS) are key…
VLT/CRIRES+ observations of warm Neptune WASP-107 b: Challenges in detecting molecules with ground-based transmission spectroscopy of cooler and cloudy exoplanets
Linn Boldt-Christmas, Adam D. Rains, Nikolai Piskunov +15
Atmospheres of transiting exoplanets can be studied spectroscopically using space-based or ground-based observations. Each has its own strengths and weaknesses, so there are benefi…
Gaia FGK Benchmark Stars: Selecting Infrared Lines for Abundance Determination
Scarlet Elgueta, Paula Jofré, Claudia Aguilera-Gómez +7
The advent of new and more powerful infrared spectrographs has significantly motivated the advancement of the study of atomic and molecular line lists and stellar atmosphere models…
Selection and characterisation of the M-dwarf targets in the PLATO Input Catalogue
L. Prisinzano, M. Montalto, G. Piotto +33
The ESA's PLAnetary Transits and Oscillations of Stars (PLATO) mission aims to detect planets orbiting around dwarfs and subgiant stars with spectral type F5 or later, including M-…
Abundance analysis of benchmark M dwarfs
T. Olander, U. Heiter, N. Piskunov +2
Abundances of M dwarfs, being the most numerous stellar type in the Galaxy, can enhance our understanding of planet formation processes. They can also be used to study the chemical…
