An Earth-sized planet with an Earth-like density
Francesco Pepe, Andrew Collier Cameron, David W. Latham +31
Kepler-78 (KIC 8435766) was identified by Sanchis-Ojeda et al. (2013) as harbouring a transiting planet of 1.16 times the size of the Earth and an orbital period of only 8.5 hours.…
Astrometric Detection of Giant Planets Around Nearby M Dwarfs: The Gaia Potential
A. Sozzetti, P. Giacobbe, M. G. Lattanzi +3
[abridged] We carry out numerical simulations to gauge the Gaia potential for precision astrometry of exoplanets orbiting a sample of known dM stars within 30 pc from the Sun. (1)…
The blue sky of GJ3470b: the atmosphere of a low-mass planet unveiled by ground-based photometry
V. Nascimbeni, G. Piotto, I. Pagano +3
GJ3470b is a rare example of a "hot Uranus" transiting exoplanet orbiting a nearby M1.5 dwarf. It is of crucial interest for atmospheric studies because it is one of the most infla…
The GAPS Programme with HARPS-N@TNG II: No giant planets around the metal-poor star HIP 11952
S. Desidera, A. Sozzetti, A. S. Bonomo +37
In the context of the program Global Architecture of Planetary Systems (GAPS), we have performed radial velocity monitoring of the metal-poor star HIP 11952 on 35 nights over about…
