LOCNES: a solar telescope to study stellar activity in the near infrared
Claudi R., Ghedina A., Pace E. +27
LOCNES (LOw-Cost NIR Extended Solar telescope) is a solar telescope installed at the TNG (Telescopio Nazionale Galileo). It feeds the light of the Sun into the NIR spectrograph GIA…
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…
Temporal evolution and correlations of optical activity indicators measured in Sun-as-a-star observations
J. Maldonado, D. F. Phillips, X. Dumusque +29
(Abridged) We perform a detailed study of the main optical activity indicators (Ca II H & K, Balmer lines, Na I D D, and He I D) measured for the Sun…
GIARPS: commissioning and first scientific results
R. Claudi, S. Benatti, I. Carleo +41
GIARPS (GIAno \& haRPS) is a project devoted to have on the same focal station of the Telescopio Nazionale Galileo (TNG) both high resolution spectrographs, HARPS-N (VIS) and GIANO…
Multi-band high resolution spectroscopy rules out the hot Jupiter BD+20 1790b - First data from the GIARPS Commissioning
I. Carleo, S. Benatti, A. F. Lanza +51
Context. Stellar activity is currently challenging the detection of young planets via the radial velocity (RV) technique. Aims. We attempt to definitively discriminate the nature o…
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…
