True Masses using RV data with Hipparcos and Gaia Astrometry
G. Piccinini, A. Petralia, A. Sozzetti +3
Long-period companions are detected and characterized thanks to long-baseline radial velocity surveys. Combining Doppler time-series with astrometry, and in particular with proper…
3D MHD simulations of coronal loops heated via magnetic braiding I. Continuous driving
Gabriele Cozzo, Paola Testa, Juan Martinez-Sykora +13
The nature and detailed properties of the heating of the million-degree solar corona are important issues that are still largely unresolved. Nanoflare heating might be dominant in…
PAStar: a model for stellar surface from the Sun to active stars
Antonino Petralia, Jesús Maldonado, Giuseppina Micela
Context. The characterization of exoplanets requires a good description of the host star. Stellar activity acts as a source of noise which can alter planet radii as derived from th…
The GAPS programme at TNG -- LXIII. Photo-evaporating puzzle: Exploring the enigmatic nature of TOI-5398 b atmospheric signal
M. C. D'Arpa, G. Guilluy, G. Mantovan +26
Atmospheric characterization is key to understanding exoplanetary systems, offering insights into the planets current and past conditions. By analyzing key lines like H alpha and t…
