The GAPS Programme at TNG XL: A puffy and warm Neptune-sized planet and an outer Neptune-mass candidate orbiting the solar-type star TOI-1422
L. Naponiello, L. Mancini, M. Damasso +55
We investigate the exoplanet candidate TOI-1422b, which was discovered by the TESS space telescope around the high proper-motion G2V star TOI-1422 ( mag), 155pc away, with…
CoRoT high-precision photometry of the B0.5 IV star HD 51756
P. I. Pápics, M. Briquet, M. Auvergne +13
OB stars are important constituents for the ecology of the Universe, and there are only a few studies on their pulsational properties detailed enough to provide important feedback…
The tip of the iceberg: the frequency content of the Delta Sct star HD 50844 from CoRoT space photometry
E. Poretti, L. Mantegazza, M. Rainer +19
It has been suggested that the detection of a wealth of very low amplitude modes in Delta Sct stars was only a matter of signal--to--noise ratio. Access to this treasure, impossibl…
The GAPS Programme with HARPS-N at TNG. XIII. The orbital obliquity of three close-in massive planets hosted by dwarf K-type stars: WASP-43, HAT-P-20 and Qatar-2
M. Esposito, E. Covino, S. Desidera +45
In the framework of the GAPS project, we are conducting an observational programme aimed at the determination of the orbital obliquity of known transiting exoplanets. The targets a…
The GAPS programme at TNG XXII. The GIARPS view of the extended helium atmosphere of HD189733 b accounting for stellar activity
G. Guilluy, V. Andretta, F. Borsa +48
Exoplanets orbiting very close to their host star are strongly irradiated. This can lead the upper atmospheric layers to expand and evaporate into space. The metastable helium (HeI…
Radial-Velocity Fitting Challenge. II. First results of the analysis of the data set
X. Dumusque, F. Borsa, M. Damasso +21
Radial-velocity (RV) signals induce RV variations an order of magnitude larger than the signal created by the orbit of Earth-twins, thus preventing their detection. The goal of thi…
