A Microphotonic Astrocomb
E. Obrzud, M. Rainer, A. Harutyunyan +13
One of the essential prerequisites for detection of Earth-like extra-solar planets or direct measurements of the cosmological expansion is the accurate and precise wavelength calib…
HADES RV Programme with HARPS-N at TNG. VII. Rotation and activity of M-Dwarfs from time-series high-resolution spectroscopy of chromospheric indicators
A. Suárez Mascareño, R. Rebolo, J. I. González Hernández +28
We aim to investigate the presence of signatures of magnetic cycles and rotation on a sample of 71 early M-dwarfs from the HADES RV programme using high-resolution time-series spec…
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…
HADES RV Programme with HARPS-N at TNG VI. GJ 3942 b behind dominant activity signals
M. Perger, I. Ribas, M. Damasso +29
Short- to mid-term magnetic phenomena on the stellar surface of M-type stars cannot only resemble the effects of planets in radial velocity data, but also may hide them. We analyze…
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@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…
