The GAPS programme at TNG LII. Spot modeling of V1298 Tau using SpotCCF tool
C. Di Maio, A. Petralia, G. Micela +27
The intrinsic variability due to the magnetic activity of young active stars is one of the main challenges in detecting and characterising exoplanets. We present a method able to m…
HD152843 b & c: the masses and orbital periods of a sub-Neptune and a super-puff Neptune

We present the characterisation of the two transiting planets around HD 152843 (TOI 2319, TIC 349488688) using an intensive campaign of HARPS-N radial velocities, and two sectors o…
A review of planetary systems around HD 99492, HD 147379 and HD 190007 with HARPS-N
M. Stalport, M. Cretignier, S. Udry +26
The Rocky Planet Search (RPS) program is dedicated to a blind radial velocity (RV) search of planets around bright stars in the Northern hemisphere, using the high-resolution echel…
The GAPS Programme at TNG: XXXVI. Measurement of the Rossiter-McLaughlin effect and revising the physical and orbital parameters of the HAT-P-15, HAT-P-17, HAT-P-21, HAT-P-26, HAT-P-29 eccentric planetary systems
L. Mancini, M. Esposito, E. Covino +34
Aim: We aim to refine the orbital and physical parameters and determine the sky-projected planet orbital obliquity of five eccentric transiting planetary systems: HAT-P-15, HAT-P-1…
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…
Optical pulsations from a transitional millisecond pulsar
F. Ambrosino, A. Papitto, L. Stella +8
Weakly magnetic, millisecond spinning neutron stars attain their very fast rotation through a 1E8-1E9 yr long phase during which they undergo disk-accretion of matter from a low ma…
The Gaia spectrophotometric standard stars survey -II. Instrumental effects of six ground-based observing campaigns
G. Altavilla, S. Marinoni, E. Pancino +16
The Gaia SpectroPhotometric Standard Stars (SPSS) survey started in 2006, it was awarded almost 450 observing nights, and accumulated almost 100,000 raw data frames, with both phot…
PAOLO: a Polarimeter Add-On for the LRS Optics at a Nasmyth focus of the TNG
S. Covino, E. Molinari, P. Bruno +10
We describe a new polarimetric facility available at the Istituto Nazionale di AstroFisica / Telescopio Nazionale Galileo at La Palma, Canary islands. This facility, PAOLO (Polarim…
Stellar Archaeology in the Galactic halo with Ultra-Faint Dwarfs: VII. Hercules
Ilaria Musella, Vincenzo Ripepi, Marcella Marconi +13
We present the first time-series study of the ultra-faint dwarf galaxy Hercules. Using a variety of telescope/instrument facilities we secured about 50 V and 80 B epochs. These dat…
Stellar Archaeology in the Galactic halo with the Ultra-Faint Dwarfs: VI. Ursa Major II
M. Dall'Ora, K. Kinemuchi, V. Ripepi +11
We present a B, V color-magnitude diagram (CMD) of the Milky Way dwarf satellite Ursa Major II (UMa II), spanning the magnitude range from V ~ 15 to V ~ 23.5 mag and extending over…
A New Census of the variable star population in the Globular Cluster NGC 2419
M. Di Criscienzo, C. Greco, V. Ripepi +6
We present B, V and I CCD light curves for 101 variable stars belonging to the globular cluster NGC2419, 60 of which are new discoveries, based on datasets obtained at the TNG, SUB…
Variable stars in the globular cluster NGC 2419
C. Greco, V. Ripepi, L. Federici +7
We have used DOLORES at the TNG to obtain B,V time series photometry of NGC 2419, one of the most distant and bright clusters in the Galactic halo. These data will be used to study…
