A lower radius and mass for the transiting extrasolar planet HAT-P-8b
L. Mancini, J. Southworth, S. Ciceri +10
Context. The extrasolar planet HAT-P-8 b was thought to be one of the more inflated transiting hot Jupiters. Aims. By using new and existing photometric data, we computed precise e…
TASTE. III. A homogeneous study of transit time variations in WASP-3b
V. Nascimbeni, A. Cunial, S. Murabito +10
The TASTE project is searching for low-mass planets with the Transit Timing Variation (TTV) technique, by gathering high-precision, short-cadence light curves for a selected sample…
A long-period massive planet around HD106515A
S. Desidera, R. Gratton, E. Carolo +9
We have performed RV monitoring of the components of the binary system HD 106515 over about 11 years using the high resolution spectrograph SARG at TNG. The primary shows long-peri…
Search for giant planets in M67 I. Overview
L. Pasquini, A. Brucalassi, M. T. Ruiz +7
Precise stellar radial velocities are used to search for massive (Jupiter masses or higher) exoplanets around the stars of the open cluster M67. We aim to obtain a census of massiv…
First Light LBT AO Images of HR 8799 bcde at 1.65 and 3.3 Microns: New Discrepancies between Young Planets and Old Brown Dwarfs
Andrew J. Skemer, Philip M. Hinz, Simone Esposito +45
As the only directly imaged multiple planet system, HR 8799 provides a unique opportunity to study the physical properties of several planets in parallel. In this paper, we image a…
LBT observations of the HR 8799 planetary system: First detection of HR8799e in H band
S. Esposito, D. Mesa, A. Skemer +33
We have performed H and Ks band observations of the planetary system around HR 8799 using the new AO system at the Large Binocular Telescope and the PISCES Camera. The excellent in…
