Characterization of the HD 17156 planetary system
M. Barbieri, R. Alonso, S. Desidera +11
AIMS : To improve the parameters of the HD 17156 system (peculiar due to the eccentric and long orbital period of its transiting planet) and constrain the presence of stellar compa…
Detection of solar-like oscillations in the G5 subgiant mu-Herculis
A. Bonanno, S. Benatti, R. Claudi +4
A clear detection of excess of power, providing a substantial evidence for solar-like oscillations in the G5 subgiant \muher{}, is presented. This star was observed over seven nigh…
Variable stars in the open cluster NGC 6791 and its surrounding field
F. De Marchi, E. Poretti, M. Montalto +7
Aims: This work presents a high--precision variability survey in the field of the old, super metal-rich open cluster NGC 6791. Methods: The data sample consists of more than 75,000…
The SARG Planet Search
S. Desidera, R. Gratton, M. Endl +6
In this chapter of the book "Planets in binaries" we summarize our recent work on the statistical properties of planets in binaries and the differences with respect to planets orbi…
A new search for planet transits in NGC 6791
M. Montalto, G. Piotto, S. Desidera +12
Context. Searching for planets in open clusters allows us to study the effects of dynamical environment on planet formation and evolution. Aims. Considering the strong dependence o…
The frequency of planets in multiple systems
M. Bonavita, S. Desidera
The frequency of planets in binaries is an important issue in the field of extrasolar planet studies, because of its relevance in estimating of the global planet population of our…
