Characterizing Stellar Flares in Ariel Targets: Activity Analysis and Transit Contamination
G. Galletta, S. Colombo, G. Micela
Stellar flares are sudden releases of magnetic energy that can distort exoplanet transit photometry and transmission spectroscopy, biasing planet radius estimates, transit timings,…
X-ray Activity of the RS CVn-type Star σ Gem with the First-Year Observations of Einstein Probe
Xuan Mao, Giuseppina Micela, Fabio Favata +3
Context. Stellar flares are energetic events driven by the sudden release of magnetic energy in the stellar atmosphere. Studying these flares is crucial for understanding their imp…
A recurrent 70-100 minute quasi-periodic pulsation in the intermediate-aged mid-M dwarf GJ 3512
J. López-Santiago, F. Reale, G. Micela +3
We report the discovery of a {recurrent} quasi-periodic pulsation (QPP) in the late-M dwarf GJ 3512 (M5.5V) using multiple TESS datasets. A strong signal with a period of 70-100 mi…
Time-resolved X-ray spectra of Proxima Centauri as seen by XMM-Newton
A. Damonte, I. Pillitteri, A. Maggio +2
Stellar soft X-ray ([1, 100] Angstrom) and Extreme Ultraviolet (also EUV, [100, 920] Angstrom; jointly, XUV) radiation affects the evolution and chemistry of exoplanet atmospheres.…
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-…
Long-term X-ray variability of the multiple-planet host L 98-59: Hints of an activity cycle
I. Pillitteri, S. Bellotti, S. Benatti +7
High-energy irradiation in X-rays and UV (XUV) can transform the planetary atmospheres through photoevaporation and photochemistry. This is more crucial for M stars, whose habitabl…
