When Do Planets Form? A Search for Extra-solar Planets Around Metal-Poor Stars
A. Sozzetti, D. W. Latham, G. Torres +4
We present preliminary results from our spectroscopic search for planets within 1 AU of metal-poor field dwarfs using NASA time with HIRES on Keck I. The core accretion model of ga…
Narrow-Angle Astrometry with the Space Interferometry Mission: The Search for Extra-Solar Planets. II. Detection and Characterization of Planetary Systems
A. Sozzetti, S. Casertano, R. A. Brown +1
(Abridged) The probability of detecting additional companions is essentially unchanged with respect to the single-planet configurations, but after fitting and subtraction of orbits…
The GAIA Astrometric Survey of the Solar Neighborhood and its Contribution to the Target Database for DARWIN/TPF
A. Sozzetti, S. Casertano, M. G. Lattanzi +1
We evaluate the potential of the ESA Cornerstone Mission GAIA in helping populate the database of nearby stars ( pc) for subsequent target selection for DARWIN/TPF. The GAI…
