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…
The GAPS Programme at TNG L -- TOI-4515 b: An eccentric warm Jupiter orbiting a 1.2 Gyr-old G-star
I. Carleo, L. Malavolta, S. Desidera +68
Context. Different theories have been developed to explain the origins and properties of close-in giant planets, but none of them alone can explain all of the properties of the war…
Masses, Revised Radii, and a Third Planet Candidate in the "Inverted" Planetary System Around TOI-1266
Ryan Cloutier, Michael Greklek-McKeon, Serena Wurmser +40
Is the population of close-in planets orbiting M dwarfs sculpted by thermally driven escape or is it a direct outcome of the planet formation process? A number of recent empirical…
HD152843 b & c: the masses and orbital periods of a sub-Neptune and a super-puff Neptune
B. A. Nicholson, S. Aigrain, N. L. Eisner +24
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…
Photometric follow-up of the 20 Myr-old multi-planet host star V1298~Tau with CHEOPS and ground-based telescopes
M. Damasso, G. Scandariato, V. Nascimbeni +25
V1298 Tau hosts at least four planets. Since its discovery, this system has been a target of intensive photometric and spectroscopic monitoring. The characterisation of its archite…
A super-massive Neptune-sized planet
L. Naponiello, L. Mancini, A. Sozzetti +55
Neptune-sized planets exhibit a wide range of compositions and densities, depending onf cators related to their formation and evolution history, such as the distance from their hos…
A compact multi-planet system transiting HIP 29442 (TOI-469) discovered by TESS and ESPRESSO. Radial velocities lead to the detection of transits with low signal-to-noise ratio
M. Damasso, J. Rodrigues, A. Castro-González +52
We followed-up with ESPRESSO the K0V star HIP 29442 (TOI-469), already known to host a validated sub-Neptune companion TOI-469.01. We aim to verify the planetary nature of TOI-469.…
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 program at TNG XLVII: The unusual formation history of V1298 Tau
D. Turrini, F. Marzari, D. Polychroni +33
Observational data from space and ground-based campaigns reveal that the 10-30 Ma old V1298 Tau star hosts a compact and massive system of four planets. Mass estimates for the two…
TOI-4010: A System of Three Large Short-Period Planets With a Massive Long-Period Companion
Michelle Kunimoto, Andrew Vanderburg, Chelsea X. Huang +53
We report the confirmation of three exoplanets transiting TOI-4010 (TIC-352682207), a metal-rich K dwarf observed by TESS in Sectors 24, 25, 52, and 58. We confirm these planets wi…
The GAPS programme at TNG. XLVI. Deep search for low-mass planets in late-dwarf systems hosting cold Jupiters
M. Pinamonti, D. Barbato, A. Sozzetti +30
We present the results of a high-cadence and high-precision radial velocity (RV) monitoring of 3 late-type dwarf stars hosting long-period giants with well-measured orbits, in orde…
XUV emission of the young planet-hosting star V1298\,Tau from coordinated observations with XMM-Newton and HST
A. Maggio, I. Pillitteri, C. Argiroffi +16
Atmospheric mass loss plays a major role in the evolution of exoplanets. This process is driven by the stellar high-energy irradiation, especially in the first hundreds of millions…
An unusually low-density super-Earth transiting the bright early-type M-dwarf GJ 1018 (TOI-244)
A. Castro-González, O. D. S. Demangeon, J. Lillo-Box +34
Small planets located at the lower mode of the bimodal radius distribution are generally assumed to be composed of iron and silicates in a proportion similar to that of the Earth.…
The GAPS Programme at TNG XLII. A characterisation study of the multi-planet system around the 400 Myr-old star HD 63433 (TOI-1726)
M. Damasso, D. Locci, S. Benatti +34
For more than two years, we monitored with the HARPS-N spectrograph the 400 Myr-old star HD\,63433, which hosts two close-in (orbital periods and days) s…
Two temperate Earth-mass planets orbiting the nearby star GJ1002
A. Suárez Mascareño, E. González-Álvarez, M. R. Zapatero Osorio +42
We report the discovery and characterisation of two Earth-mass planets orbiting in the habitable zone of the nearby M-dwarf GJ~1002 based on the analysis of the radial-velocity (RV…

J. Blanco-Pozo, M. Perger, M. Damasso +37
Detecting a planetary companion in a short-period orbit through radio emission from the interaction with its host star is a new prospect in exoplanet science. Recently, a tantalisi…
