Report by the ESA-ESO Working Group on Extra-Solar Planets
M. Perryman, O. Hainaut, D. Dravins +14
Various techniques are being used to search for extra-solar planetary signatures, including accurate measurement of radial velocity and positional (astrometric) displacements, grav…
A direct imaging search for wide (sub)stellar companions around rad-vel planet host stars
M. Mugrauer, R. Neuhäuser, T. Mazeh +3
We present an overview of our ongoing systematic search for wide (sub)stellar companions around the stars known to host rad-vel planets. By using a relatively large field of view a…
A Possible Correlation between Mass Ratio and Period Ratio in Multiple Planetary Systems
Tsevi Mazeh, Shay Zucker
We report on a possible correlation between the mass ratio and period ratio of pairs of adjacent planets in extra-solar planetary systems. Monte-Carlo simulations show that the eff…
A Statistical Analysis of The Extrasolar Planets and The Low-Mass Secondaries
Tsevi Mazeh, Shay Zucker
We show that the astrometric Hipparcos data of the stars hosting planet candidates are not accurate enough to yield statistically significant orbits. Therefore, the recent suggesti…
A Planet Candidate in the Stellar Triple System HD178911
S. Zucker, D. Naef, D. W. Latham +9
We report the detection of a low-mass companion orbiting the solar-type star HD178911B, the distant component of the stellar triple system HD178911. The variability of HD178911B wa…
Analysis of the Hipparcos Observations of the Extrasolar Planets and the Brown-Dwarf Candidates
Shay Zucker, Tsevi Mazeh
We analyzed the Hipparcos astrometric observations of 47 stars that were discovered to harbor giant planets and 14 stars with brown-dwarf secondary candidates. The Hipparcos measur…
