A decade of monitoring the HIP 41378's planetary system
S. Grouffal, A. Santerne, X. Dumusque +32
Multi-planetary systems provide key constraints on planet formation and evolution, as their architecture encodes the dynamical history of planets formed within a common protoplanet…
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…
Kepler-102: Masses and Compositions for a Super-Earth and Sub-Neptune Orbiting an Active Star
Casey Brinkman, James Cadman, Lauren Weiss +24
Radial velocity (RV) measurements of transiting multiplanet systems allow us to understand the densities and compositions of planets unlike those in the Solar System. Kepler-102, w…
Independent validation of the temperate Super-Earth HD79211 b using HARPS-N
Victoria DiTomasso, Chantanelle Nava, Mercedes López-Morales +28
We present high-precision radial velocities (RVs) from the HARPS-N spectrograph for HD79210 and HD79211, two M0V members of a gravitationally-bound binary system. We detect a plane…
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…
Wolf 503 b: Characterization of a Sub-Neptune Orbiting a Metal-Poor K Dwarf
Alex S. Polanski, Ian J. M. Crossfield, Jennifer A. Burt +35
Using radial velocity measurements from four instruments, we report the mass and density of a sub-Neptune orbiting the quiet K-dwarf Wolf 503 (HIP…
The GAPS programme at TNG XXX. Atmospheric Rossiter-McLaughlin effect and atmospheric dynamics of KELT-20b
M. Rainer, F. Borsa, L. Pino +30
Transiting ultra-hot Jupiters are ideal candidates to study the exoplanet atmospheres and their dynamics, particularly by means of high-resolution, high signal-to-noise ratio spect…
TOI-1634 b: an Ultra-Short Period Keystone Planet Sitting Inside the M Dwarf Radius Valley
R. Cloutier, D. Charbonneau, K. G. Stassun +63
Studies of close-in planets orbiting M dwarfs have suggested that the M dwarf radius valley may be well-explained by distinct formation timescales between enveloped terrestrials, a…
The GAPS Programme at TNG -- XXIII. HD 164922 d: a close-in super-Earth discovered with HARPS-N in a system with a long-period Saturn mass companion
S. Benatti, M. Damasso, S. Desidera +41
In the framework of the Global Architecture of Planetary Systems (GAPS) project we collected more than 300 spectra with HARPS-N at the TNG for the bright G9V star HD164922. This ta…
A pair of TESS planets spanning the radius valley around the nearby mid-M dwarf LTT 3780
Ryan Cloutier, Jason D. Eastman, Joseph E. Rodriguez +84
We present the confirmation of two new planets transiting the nearby mid-M dwarf LTT 3780 (TIC 36724087, TOI-732, , , =0.374 R, =0.401 M$_{\…
The GAPS Programme at TNG XXI -- A GIARPS case-study of known young planetary candidates: confirmation of HD 285507 b and refutation of AD Leo b
I. Carleo, L. Malavolta, A. F. Lanza +67
The existence of hot Jupiters is still not well understood. Two main channels are thought to be responsible for their current location: a smooth planet migration through the proto-…
The GAPS Programme with HARPS-N at TNG VIII: Observations of the Rossiter-McLaughlin effect and characterisation of the transiting planetary systems HAT-P-36 and WASP-11/HAT-P-10
L. Mancini, M. Esposito, E. Covino +36
We determine the true and the projected obliquity of HAT-P-36 and WASP-11/HAT-P-10 systems, respectively, which are both composed of a relatively cool star and a hot-Jupiter planet…
The GAPS Programme with HARPS-N@TNG VI: The Curious Case of TrES-4b
A. Sozzetti, A. S. Bonomo, K. Biazzo +38
We revisit the TrES-4 system parameters based on high-precision HARPS-N radial-velocity measurements and new photometric light curves. A combined spectroscopic and photometric anal…
Characterization of the Kepler-101 planetary system with HARPS-N. A hot super-Neptune with an Earth-sized low-mass companion
A. S. Bonomo, A. Sozzetti, C. Lovis +32
We report on the characterization of the Kepler-101 planetary system, thanks to a combined DE-MCMC analysis of Kepler data and forty radial velocities obtained with the HARPS-N spe…
A long-period massive planet around HD106515A
S. Desidera, R. Gratton, E. Carolo +9
We have performed RV monitoring of the components of the binary system HD 106515 over about 11 years using the high resolution spectrograph SARG at TNG. The primary shows long-peri…
