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…

Separating planetary reflex Doppler shifts from stellar variability in the wavelength domain

A. Collier Cameron, E. B. Ford, S. Shahaf +28

Stellar magnetic activity produces time-varying distortions in the photospheric line profiles of solar-type stars. These lead to systematic errors in high-precision radial-velocity…

The GAPS Programme at TNG -- XXV. Stellar atmospheric parameters and chemical composition through GIARPS optical and near-infrared spectra

M. Baratella, V. D'Orazi, K. Biazzo +20

The detailed chemical composition of stars is important in many astrophysical fields, among which the characterisation of exoplanetary systems. Previous studies seem to indicate an…

TOI-1235 b: a keystone super-Earth for testing radius valley emergence models around early M dwarfs

Ryan Cloutier, Joseph E. Rodriguez, Jonathan Irwin +85

Small planets on close-in orbits tend to exhibit envelope mass fractions of either effectively zero or up to a few percent depending on their size and orbital period. Models of the…

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…

The lowest frequency Fast Radio Bursts: Sardinia Radio Telescope detection of the periodic FRB 180916 at 328 MHz

M. Pilia, M. Burgay, A. Possenti +35

We report on the lowest-frequency detection to date of three bursts from the fast radio burst FRB 180916, observed at 328 MHz with the Sardinia Radio Telescope (SRT). The SRT obser…
