Age consistency between exoplanet hosts and field stars
Andrea Bonfanti, Sergio Ortolani, Valerio Nascimbeni
Transiting planets around stars are discovered mostly through photometric surveys. Unlike radial velocity surveys, photometric surveys do not tend to target slow rotators, inactive…
Broad-band spectrophotometry of the hot Jupiter HAT-P-12b from the near-UV to the near-IR
M. Mallonn, V. Nascimbeni, J. Weingrill +13
The detection of trends or gradients in the transmission spectrum of extrasolar planets is possible with observations at very low spectral resolution. Transit measurements of suffi…
The M4 Core Project with HST - IV. Internal Kinematics from Accurate Radial Velocities of 2771 Cluster Members
L. Malavolta, G. Piotto, L. R. Bedin +3
We present a detailed study of the internal kinematics of the Galactic Globular Cluster M 4 (NGC 6121), by deriving the radial velocities from 7250 spectra for 2771 stars distribut…
The GAPS Programme with HARPS-N@TNG IX. The multi-planet system KELT-6: detection of the planet KELT-6 c and measurement of the Rossiter-McLaughlin effect for KELT-6 b
M. Damasso, M. Esposito, V. Nascimbeni +39
Aims. For more than 1.5 years we monitored spectroscopically the star KELT-6 (BD+312447), known to host the transiting hot Saturn KELT-6b, because a previously observed long-term t…
The HARPS-N Rocky Planet Search I. HD219134b: A transiting rocky planet in a multi-planet system at 6.5 pc from the Sun
F. Motalebi, S. Udry, M. Gillon +36
We present here the detection of a system of four low-mass planets around the bright (V=5.5) and close-by (6.5 pc) star HD219134. This is the first result of the Rocky Planet Searc…
Large Binocular Telescope view of the atmosphere of GJ1214b
V. Nascimbeni, M. Mallonn, G. Scandariato +8
The atmospheric composition and vertical structure of the super-Earth GJ1214b has been a subject of debate since its discovery in 2009. Recent studies have indicated that high-alti…
High-precision astrometry with VVV. I. An independent reduction pipeline for VIRCAM@VISTA
M. Libralato, A. Bellini, L. R. Bedin +6
We present a new reduction pipeline for the VIRCAM@VISTA detector and describe the method developed to obtain high-precision astrometry with the VISTA Variables in the Vía Láctea (…
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…
The GAPS Programme with HARPS-N@TNG V. A comprehensive analysis of the XO-2 stellar and planetary systems
M. Damasso, K. Biazzo, A. S. Bonomo +56
XO-2 is the first confirmed wide stellar binary system where the almost twin components XO-2N and XO-2S have planets. This stimulated a detailed characterization study of the stell…
