Chemical fingerprints of hot Jupiter planet formation
J. Maldonado, E. Villaver, C. Eiroa
The current paradigm to explain the presence of Jupiters with small orbital periods (P 10 days; hot Jupiters) that involves their formation beyond the snow line following inwar…
GIARPS@TNG GIANO-B & HARPS-N together for a wider wavelength range spectroscopy
R. Claudi, S. Benatti, I. Carleo +36
Since 2012, thanks to the installation of the high resolution echelle spectrograph in the optical range HARPS-N, the Italian telescope TNG (La Palma) became one of the key faciliti…
The GAPS Programme with HARPS-N at TNG XV. A substellar companion around a K giant star identified with quasi-simultaneous HARPS-N and GIANO measurements
E. González - Álvarez, L. Affer, G. Micela +34
Context. Identification of planetary companions of giant stars is made difficult because of the astrophysical noise, that may produce radial velocity (RV) variations similar to tho…
The GAPS Programme with HARPS-N@TNG XIV. Investigating giant planet migration history via improved eccentricity and mass determination for 231 transiting planets
A. S. Bonomo, S. Desidera, S. Benatti +34
We carried out a Bayesian homogeneous determination of the orbital parameters of 231 transiting giant planets (TGPs) that are alone or have distant companions; we employed DE-MCMC…
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…
Searching for chemical signatures of brown dwarf formation
J. Maldonado, E. Villaver
Recent studies have shown that close-in brown dwarfs in the mass range 35-55 M are almost depleted as companions to stars, suggesting that objects with masses above and…
