The GAPS Programme at TNG. LXXX. Characterisation of the 400 Myr old multi-planet system K2-233
V. Fardella, S. Benatti, R. Spinelli +27
Understanding exoplanet physical properties is crucial for characterising their atmospheres and internal composition. Precise planetary masses are essential for constraining bulk d…
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…
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…
The GAPS Programme at TNG: LIV. A HeI survey of close-in giant planets hosted by M-K dwarf stars with GIANO-B
G. Guilluy, M. C. D'Arpa, A. S. Bonomo +30
Atmospheric escape plays a fundamental role in shaping the properties of exoplanets. The metastable near-infrared helium triplet at 1083.3 nm (HeI) is a powerful proxy of extended…
A reanalysis of the LHS 1140 b atmosphere observed with the Hubble Space Telescope
Alfredo Biagini, Gianluca Cracchiolo, Antonino Petralia +3
The super-Earth LHS 1140 b is an interesting target for atmospheric observations since it is close to the habitable zone of its star and falls in the gap of the radius distribution…
Signatures of X-ray dominated chemistry in the spectra of exoplanetary atmospheres
Daniele Locci, Giambattista Aresu, Antonino Petralia +3
High-energy radiation from stars impacts planetary atmospheres deeply affecting their chemistry, providing departures from chemical equilibrium. While the upper atmospheric layers…
Correcting Exoplanet Transmission Spectra for Stellar Activity with an Optimised Retrieval Framework
Alexandra Thompson, Alfredo Biagini, Gianluca Cracchiolo +7
The chromatic contamination that arises from photospheric heterogeneities e.g. spots and faculae on the host star presents a significant noise source for exoplanet transmission spe…
HADES RV Programme with HARPS-N at TNG XV. Planetary occurrence rates around early-M dwarfs
M. Pinamonti, A. Sozzetti, J. Maldonado +28
We present the complete Bayesian statistical analysis of the HArps-n red Dwarf Exoplanet Survey (HADES), which monitored the radial velocities of a large sample of M dwarfs with HA…
Extreme ultraviolet and X-ray driven photochemistry of gaseous exoplanets
Daniele Locci, Antonino Petralia, Giuseppina Micela +3
The interaction of exoplanets with their host stars causes a vast diversity in bulk and atmospheric compositions, and physical and chemical conditions. Stellar radiation, especiall…
HADES RV Programme with HARPS-N at TNG XIII. A sub-Neptune around the M dwarf GJ 720 A
E. González-Álvarez, A. Petralia, G. Micela +21
Context. The high number of super-Earth and Earth-like planets in the habitable zone (HZ) detected around M-dwarf stars in the last years has revealed these stellar objects to be t…
A systematic study of \ce{CO2} planetary atmospheres and their link to the stellar environment
A. Petralia, E. Alei, G. Aresu +5
The Milky Way Galaxy is literally teeming with exoplanets; thousands of planets have been discovered, with thousands more planet candidates identified. Terrestrial-like planets are…
X-Raying the Dark Side of Venus - Scatter from Venus Magnetotail?
M. Afshari, G. Peres, P. R. Jibben +3
This work analyzes the X-ray, EUV and UV emission apparently coming from the Earth-facing (dark) side of Venus as observed with Hinode/XRT and SDO/AIA during a transit across the s…
