The PLATO 2.0 mission
PLATO 2.0 has recently been selected for ESA’s M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it addresses
The GAPS Programme with HARPS-N at TNG - XIV. Investigating giant planet migration history via improved eccentricity and mass determination for 231 transiting planets
We carried out a Bayesian homogeneous determination of the orbital parameters of 231 transiting giant planets (TGPs) that are alone or have distant companions; we employed differential evolution
Growth model interpretation of planet size distribution
Significance The discovery of numerous exoplanet systems containing diverse populations of planets orbiting very close to their host stars challenges the planet formation theories based on the solar
A path towards understanding the rotation-activity relation of M dwarfs with K2 mission, X-ray and UV data
We would especially like to thank A. Vanderburg for his public release of the analysed K2 light curves, upon which much of the present work is based. We thank the anonymous referee for a very careful
The GAPS Programme with HARPS-N at TNG. X. Differential abundances in the XO-2 planet hosting binary
Binary stars hosting exoplanets are a unique laboratory where chemical tagging can be performed to measure with high accuracy the elemental abundances of both stellar components, with the aim to
Stellar parameters of early M dwarfs from ratios of spectral features at optical wavelengths
(Abridged) Low-mass stars have been recognised as promising targets in the search for rocky, small planets with the potential of supporting life. Doppler search programmes using high-resolution
A low-mass planet candidate orbiting Proxima Centauri at a distance of 1.5 AU
It is shown that the existence of the planet can be ascertained, and its true mass can be determined with high accuracy, by combining Gaia astrometry and radial velocities, and the candidate planet represents a challenge for the models of super-Earth formation and evolution.
The GAPS programme with HARPS-N at TNG - I. Observations of the Rossiter-McLaughlin effect and characterisation of the transiting system Qatar-1
Context. Our understanding of the formation and evolution of planetary systems is still fragmentary because most of the current data provide limited information about the orbital structure and
The GAPS programme with HARPS-N at TNG - VII. Putting exoplanets in the stellar context: magnetic activity and asteroseismology of τ Bootis A
Aims. We observed the τ Boo system with the HARPS-N spectrograph to test a new observational strategy aimed at jointly studying asteroseismology, the planetary orbit, and star-planet magnetic
TASTE: The Asiago Search for Transit timing variations of Exoplanets I. Overview and improved parameters for HAT-P-3b and HAT-P-14b
A promising method for detecting earth-sized exoplanets is the timing analysis of a known transit. The technique allows a search for variations in either the transit duration or the center induced by
