Observing exoplanets from the planet Earth: how our revolution around the Sun affects the detection of 1-year periods
Federico Borin, Ennio Poretti, Francesco Borsa +1
We analysed a selected sample of exoplanets with orbital periods close to 1 year to study the effects of the spectral window on the data, affected by the 1 cycle/year aliasing due…
The GAPS Project: First Results
S. Benatti, R. Claudi, S. Desidera +14
The GAPS programme is an Italian project aiming to search and characterize extra-solar planetary systems around stars with different characteristics (mass, metallicity, environment…
Interferometric and spectroscopic observations of the BRITE target Delta Cep
Ennio Poretti, Nicolas Nardetto
We used new HARPS-N spectra to revisitate the projection factor of Delta Cep and to directly measure the specific contribution of the velocity gradient within the atmosphere. By in…
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…
Photometric and spectroscopic variability of the B5IIIe star HD 171219
L. Andrade, E. Janot-Pacheco, M. Emilio +11
We analyzed the star HD 171219, one of the relatively bright Be stars observed in the seismo field of the CoRoT satellite, in order to determine its physical and pulsation characte…
