The PLATO Science Calibration and Validation Plan: Targets for the First Long-pointing Field
Konstanze Zwintz, Conny Aerts, Andrew Tkachenko +56
In order to meet the science goals of the PLATO space mission, an extensive science calibration and validation plan has been designed. This paper describes this plan, as well as th…
The GAPS Programme at TNG. LXI. Atmospheric parameters and elemental abundances of TESS young exoplanet host stars
S. Filomeno, K. Biazzo, M. Baratella +26
The study of exoplanets at different evolutionary stages can shed light on their formation, migration, and evolution. The determination of exoplanet properties depends on the prope…
The curious case of 2MASS J15594729+4403595, an ultra-fast M2 dwarf with possible Rieger cycles
S. Messina, G. Catanzaro, A. F. Lanza +4
RACE-OC (Rotation and ACtivity Evolution in Open Clusters) is a project aimed at characterising the rotational and magnetic activity properties of the late-type members of open clu…
The GAPS Programme at TNG. LIX. A characterisation study of the 300 Myr old multi-planetary system orbiting the star BD+40 2790 (TOI-2076)
M. Damasso, D. Locci, S. Benatti +35
We collected more than 300 high-resolution spectra of the 300 Myr old star BD+40 2790 (TOI-2076) over ~3 years. This star hosts three transiting planets discovered by TESS, with or…
Mass determination of two Jupiter-sized planets orbiting slightly evolved stars: TOI-2420 b and TOI-2485 b
Ilaria Carleo, Oscar Barrágan, Carina M. Persson +67
Hot and warm Jupiters might have undergone the same formation and evolution path, but the two populations exhibit different distributions of orbital parameters, challenging our und…
Measuring stellar surface rotation and activity with the PLATO mission -- I. Strategy and application to simulated light curves
S. N. Breton, A. F Lanza, S. Messina +20
The Planetary Transits and Oscillations of stars mission (PLATO) will allow us to measure surface rotation and monitor photometric activity of tens of thousands of main sequence so…
