The GAPS Programme at TNG. XXXII. The revealing non-detection of metastable HeI in the atmosphere of the hot Jupiter WASP-80b
L. Fossati, G. Guilluy, I. F. Shaikhislamov +38
The hot Jupiter WASP-80b has been identified as a possible excellent target for detecting and measuring HeI absorption in the upper atmosphere. We observed 4 primary transits of WA…
Accretion processes in the galaxy cluster Hydra A/Abell 780
M. Girardi, W. Boschin, M. Nonino +2
Clusters of galaxies evolve and accrete mass, mostly from small galaxy systems. Our aim is to study the velocity field of the galaxy cluster Abell 780, which is known for the power…
Fundamental physics with ESPRESSO: Precise limit on variations in the fine-structure constant towards the bright quasar HE 05154414
Michael T. Murphy, Paolo Molaro, Ana C. O. Leite +40
The strong intervening absorption system at redshift 1.15 towards the very bright quasar HE 05154414 is the most studied absorber for measuring possible cosmological variations…
K2-79b and K2-222b: Mass measurements of two small exoplanets with periods beyond 10 days that overlap with periodic magnetic activity signals
Chantanelle Nava, Mercedes López-Morales, Annelies Mortier +28
We present mass and radius measurements of K2-79b and K2-222b, two transiting exoplanets orbiting active G-type stars. Their respective 10.99d and 15.39d orbital periods fall near…
Stellar Population Astrophysics (SPA) with the TNG: Stock 2, a little-studied open cluster with an eMSTO
J. Alonso-Santiago, A. Frasca, G. Catanzaro +14
Stock 2 is a little-studied open cluster that shows an extended main-sequence turnoff (eMSTO). In order to investigate this phenomenon and characterise the cluster itself we perfor…
HD22496b: the first ESPRESSO standalone planet discovery
J. Lillo-Box, J. P. Faria, A. Suárez Mascareño +32
The ESPRESSO spectrograph is a new powerful tool to detect and characterize extrasolar planets. Its design allows unprecedented radial velocity precision (down to a few tens of cm/…
