The magnetically quiet solar surface dominates HARPS-N solar RVs during low activity
Ben S. Lakeland, Tim Naylor, Raphaëlle Haywood +15
Using images from the Helioseismic and Magnetic Imager aboard the \textit{Solar Dynamics Observatory} (SDO/HMI), we extract the radial-velocity (RV) signal arising from the suppres…
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…
A hot mini-Neptune and a temperate, highly eccentric sub-Saturn around the bright K-dwarf TOI-2134
F. Rescigno, G. Hébrard, A. Vanderburg +64
We present the characterisation of an inner mini-Neptune in a 9.22920050.0000063 day orbit and an outer mono-transiting sub-Saturn planet in a 95.50 day orbi…
TESS Spots a Super-Puff: The Remarkably Low Density of TOI-1420b
Stephanie Yoshida, Shreyas Vissapragada, David W. Latham +51
We present the discovery of TOI-1420b, an exceptionally low-density ( g cm) transiting planet in a day orbit around a late G dwarf star. Using tra…
The Extreme Stellar-Signals Project III. Combining Solar Data from HARPS, HARPS-N, EXPRES, and NEID
Lily L. Zhao, Xavier Dumusque, Eric B. Ford +37
We present an analysis of Sun-as-a-star observations from four different high-resolution, stabilized spectrographs -- HARPS, HARPS-N, EXPRES, and NEID. With simultaneous observatio…
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…
Sub-m s upper limits from a deep HARPS-N radial-velocity search for planets orbiting HD 166620 and HD 144579
Ancy Anna John, Andrew Collier Cameron, João P. Faria +3
Minimising the impact of stellar variability in Radial Velocity (RV) measurements is a critical challenge in achieving the 10 cm s precision needed to hunt for Earth twins.…
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…
Simultaneous and panchromatic observations of the Fast Radio Burst FRB 20180916B
M. Trudu, M. Pilia, L. Nicastro +47
Aims. Fast Radio Bursts are bright radio transients whose origin has not yet explained. The search for a multi-wavelength counterpart of those events can put a tight constrain on t…
Hyades Member K2-136c: The Smallest Planet in an Open Cluster with a Precisely Measured Mass
Andrew W. Mayo, Courtney D. Dressing, Andrew Vanderburg +39
K2-136 is a late-K dwarf ( M) in the Hyades open cluster with three known, transiting planets and an age of Myr. Analyzing K2 photometry, we found…
The optical imager Galileo (OIG)
Bortoletto F., Benetti S., Bonanno G. +9
The present paper describes the construction, the installation and the operation of the Optical Imager Galileo (OIG), a scientific instrument dedicated to the 'imaging' in the visi…
The commissioning phase
F. Bortoletto, S. Benetti, G. Bonanno +34
In May 1997 a consistent part of the services and structures committed to the industry had already been released to the commissioning group. The telescope itself was, with the exce…
