New constraints on the future evaporation of the young exoplanets in the V1298 Tau system
A. Maggio, D. Locci, I. Pillitteri +7
Transiting planets at young ages are key targets for improving our understanding of the evolution of exo-atmospheres. We present results of a new X-ray observation of V1298 Tau wit…
Rapid contraction of giant planets orbiting the 20 million-years old star V1298 Tau
A. Suárez Mascareño, M. Damasso, N. Lodieu +41
Current theories of planetary evolution predict that infant giant planets have large radii and very low densities before they slowly contract to reach their final size after about…
Faint objects in motion: the new frontier of high precision astrometry
Fabien Malbet, Céline Boehm, Alberto Krone-Martins +83
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
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…
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/…
Warm terrestrial planet with half the mass of Venus transiting a nearby star
Olivier D. S. Demangeon, M. R. Zapatero Osorio, Y. Alibert +42
The advent of a new generation of radial velocity instruments has allowed us to break the one Earth-mass barrier. We report a new milestone in this context with the detection of th…
A HARPS-N mass for the elusive Kepler-37d: a case study in disentangling stellar activity and planetary signals
V. M. Rajpaul, L. A. Buchhave, G. Lacedelli +22
To date, only 18 exoplanets with radial velocity (RV) semi-amplitudes m/s have had their masses directly constrained. The biggest obstacle to RV detection of such exoplanets i…
A new photometric and dynamical study of the eclipsing binary star HW Virginis
S. B. Brown-Sevilla, V. Nascimbeni, L. Borsato +12
A growing number of eclipsing binary systems of the "HW Vir" kind (i. e., composed by a subdwarf-B/O primary star and an M dwarf secondary) show variations in their orbital period,…
HADES RV programme with HARPS-N at TNG XIV. A candidate super-Earth orbiting the M-dwarf GJ 9689 with a period close to half the stellar rotation period
J. Maldonado, A. Petralia, M. Damasso +27
Context. It is now well-established that small, rocky planets are common around low-mass stars. However, the detection of such planets is challenged by the short-term activity of t…
The ultra-hot-Jupiter KELT-16 b: Dynamical Evolution and Atmospheric Properties
L. Mancini, J. Southworth, L. Naponiello +15
We present broad-band photometry of 30 planetary transits of the ultra-hot Jupiter KELT-16b, using five medium-class telescopes. The transits were monitored through standard B, V,…
Five carbon- and nitrogen-bearing species in a hot giant planet's atmosphere
Paolo Giacobbe, Matteo Brogi, Siddharth Gandhi +40
The atmospheres of gaseous giant exoplanets orbiting close to their parent stars (hot Jupiters) have been probed for nearly two decades. They allow us to investigate the chemical a…
HADES RV Programme with HARPS-N at TNG XIII. A sub-Neptune around the M dwarf GJ 720 A
E. González-Álvarez, A. Petralia, G. Micela +21
Context. The high number of super-Earth and Earth-like planets in the habitable zone (HZ) detected around M-dwarf stars in the last years has revealed these stellar objects to be t…
Constraints on the mass and atmospheric composition and evolution of the low-density young planet DS Tuc A b
S. Benatti, M. Damasso, F. Borsa +9
We performed a radial velocity (RV) monitoring of the 40 Myr old star DS Tuc A with HARPS at the ESO-3.6m to determine the planetary mass of its 8.14-days planet, first revealed by…
A sub-Neptune and a non-transiting Neptune-mass companion unveiled by ESPRESSO around the bright late-F dwarf HD 5278 (TOI-130)
A. Sozzetti, M. Damasso, A. S. Bonomo +45
[Abridged] We exploit the extreme radial velocity (RV) precision of the ultra-stable echelle spectrograph ESPRESSO on the VLT to unveil the physical properties of the transiting su…
Six transiting planets and a chain of Laplace resonances in TOI-178
A. Leleu, Y. Alibert, N. C. Hara +152
Determining the architecture of multi-planetary systems is one of the cornerstones of understanding planet formation and evolution. Resonant systems are especially important as the…
