Metallicities in M dwarfs: Investigating different determination techniques
V. M. Passegger, A. Bello-García, J. Ordieres-Meré +17
Deriving metallicities for solar-like stars follows well-established methods, but for cooler stars such as M dwarfs, the determination is much more complicated due to forests of mo…
SWEET-Cat 2.0: The Cat just got SWEETer; Higher quality spectra and precise parallaxes from GAIA eDR3
S. G. Sousa, V. Adibekyan, E. Delgado-Mena +13
Aims. The catalog of Stars With ExoplanETs (SWEET-Cat) was originally introduced in 2013. Since then many more exoplanets have been confirmed, increasing significantly the number o…
The homogeneous characterisation of Ariel host stars
C. Danielski, A. Brucalassi, S. Benatti +20
The Ariel mission will characterise the chemical and thermal properties of the atmospheres of about a thousand exoplanets transiting their host star(s). The observation of such a l…
The Gaia-ESO survey: Mixing processes in low-mass stars traced by lithium abundance in cluster and field stars
L. Magrini, N. Lagarde, C. Charbonnel +42
We aim to constrain the mixing processes in low-mass stars by investigating the behaviour of the Li surface abundance after the main sequence. We take advantage of the data from th…
TESS and HARPS reveal two sub-Neptunes around TOI 1062
J. F. Otegi, F. Bouchy, R. Helled +46
The Transiting Exoplanet Survey Satellite (\textit{TESS}) mission was designed to perform an all-sky search of planets around bright and nearby stars. Here we report the discovery…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
A hot mini-Neptune in the radius valley orbiting solar analogue HD 110113
H. P. Osborn, D. J. Armstrong, L. D. Nielsen +53
We report the discovery of HD 110113 b (TOI-755.01), a transiting mini-Neptune exoplanet on a 2.5-day orbit around the solar-analogue HD 110113 (Teff = 5730K). Using TESS photometr…
Determination of stellar parameters for Ariel targets: a comparison analysis between different spectroscopic methods
A. Brucalassi, M. Tsantaki, L. Magrini +9
Ariel has been selected as the next ESA M4 science mission and it is expected to be launched in 2028. During its 4-year mission, Ariel will observe the atmospheres of a large and d…
