Searching for hot water world candidates with CHEOPS: II. A low-density super-Earth orbiting the K dwarf TOI-2211
J. A. Egger, P. Cortés-Zuleta, D. Kubyshkina +98
Small exoplanets on close-in orbits are exposed to high levels of stellar irradiation, which can effectively remove low-mass primordial H/He envelopes through atmospheric escape. U…
Toward the Italian Astronomical Community's Contribution to HWO: Science, Technology, and Instrument Concepts
A. Fontana, F. Annibali, N. Antonietti +101
This paper summarizes the interest of the Italian astronomical community in the possible participation in the development of the Habitable Worlds Observatory (HWO). It is largely b…
The GAPS programme at TNG LXXIX. New mass constraints for the infant planets in the V1298 Tau system through a long-term radial velocity monitoring with HARPS-N
M. Damasso, P. Leonardi, L. Borsato +26
We aim to constrain the dynamical masses of the four confirmed transiting planets orbiting the infant ( Myr) star V1298,Tau (orbital periods 24.1 d, 8.2…
CHEOPS photometry from 2024 reveals a reversal in the transit-timing variations of AU Mic c
Z. Garai, Gy. M. Szabó, D. Gandolfi +90
We present new CHEOPS transit observations of AU Mic b and AU Mic c obtained between June and September 2024, extending the baseline of transit-timing measurements of this young pl…
The GAPS programme at TNG: LXXVI. TOI-1533: a compact system hosting a super-Neptune-mass pair with disparate radii
G. Mantovan, V. Nascimbeni, S. Desidera +49
The present-day architecture of planetary systems contains information about their formation and migration histories. The origin of hot Jupiters (HJs, P 10 d, $R_{\rm p}…
An Ultra-Short Period Super-Earth and a Sub-Neptune Orbiting the K dwarf TOI-4311
Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrew Collier Cameron +95
We report the discovery and characterisation of the multi-planetary system around TOI-4311, a K dwarf kinematically between the Galactic thick disk and Hercules stream. TOI-4311 ho…
The PLATO field selection process III. Selection of the Prime Sample for the LOPS2 field
V. Nascimbeni, G. Piotto, V. Granata +30
The PLanetary Transits and Oscillations of stars (PLATO) mission will begin its four-year nominal mission in early 2027 by monitoring its Long-duration Observation Phase field at S…
TOI-159 b: an eccentric hot-Jupiter planet around a young, pulsating Doradus star
G. Mantovan, A. Llancaqueo Albornoz, A. Psaridi +16
Fast-rotating hot stars are challenging targets for exoplanet searches due to rotational broadening and stellar variability. Moreover, hot stars often exhibit pulsations, an additi…
A tidally detached super Neptune on a strongly misaligned retrograde orbit
G. Mantovan, L. Malavolta, A. F. Lanza +18
The obliquity between a planet's orbital axis and its host star's spin axis provides crucial insights into planetary formation and migration. Planets with scaled semi-major axes ($…
The multi-planet system TOI-5624: Four transiting sub-Neptunes with an outer companion revealed by transit-timing variations
A. Bonfanti, D. Gandolfi, P. Leonardi +96
Following the 2022 alert of a TESS object of interest transiting TOI-5624 (a G7 V star 100 pc away), a CHEOPS campaign in 2023 detected four planetary signals at $P_b\approx3…
Assessment of PLATO Science Performance
Juan Cabrera, Heike Rauer, Reza Samadi +121
The PLATO mission is scheduled for launch early 2027. In this paper we present an overview of the performance drivers for the mission at the time where all flight models of the cam…
The PLATO Input Catalogue of targets (tPIC) for the first Long Pointing Field
M. Montalto, G. Piotto, P. M. Marrese +31
The ESA PLAnetary Transits and Oscillations of stars (PLATO) mission is designed to detect terrestrial planets in the habitable zones of solar-type stars. Owing to telemetry constr…
Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…
