Among the hundred or so extrasolar planets discovered to date, 19 are orbiting a component of a double or multiple star system. In this paper, we discuss the properties of these planets and compare them to the characteristics of planets orbiting isolated stars. Although the sample of planets found in multiple star systems is not large, some differences between the orbital parameters and the masses of these planets and the ones of planets orbiting single stars are emerging in the mass-period and…

Eccentricities of Planets in Binary Systems
The most puzzling property of the extrasolar planets discovered by recent radial velocity surveys is their high orbital eccentricities, which are very difficult to explain within our current
Statistical Properties of Exoplanets
Since the detection a decade ago of the planetary companion of 51 Peg, more than 200 extrasolar planets have been unveiled, mostly by radial-velocity measurements but also in a few cases by
Statistical properties of exoplanets IV. The period-eccentricity relations of exoplanets and of binary stars
A sample of spectroscopic binaries and a sample of single planetary systems, both having main-sequence solar-type primary components, are selected in order to compare their eccentricities. The
Planetary Systems in Binaries. I. Dynamical Classification
Many recent observational studies have concluded that planetary systems commonly exist in multiple-star systems. At least ~20% of the known extrasolar planetary systems are associated with one or
The frequency of planets in multiple systems
Context. 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 Galaxy and
Extrasolar Planets in Double and Multiple Stellar Systems
About 60% of G and K dwarfs belong to double or multiple stellar systems, making these a common environment in which planets may form. Despite this, close binaries have often been rejected from
Extrasolar planets in stellar multiple systems
Aims. Analyzing exoplanets detected by radial velocity (RV) or transit observations, we determine the multiplicity of exoplanet host stars in order to study the influence of a stellar companion on
High Orbital Eccentricities of Extrasolar Planets Induced by the Kozai Mechanism
One of the most remarkable properties of extrasolar planets revealed by the ongoing radial velocity surveys is their high orbital eccentricities, which are difficult to explain with our current
Planets in Binaries: Formation and Dynamical Evolution
Binary systems are very common among field stars, yet the vast majority of known exoplanets have been detected around single stars. While this relatively small number of planets in binaries is
Limits on Stellar Companions to Exoplanet Host Stars with Eccentric Planets
Though there are now many hundreds of confirmed exoplanets known, the binarity of exoplanet host stars is not well understood. This is particularly true of host stars that harbor a giant planet in a


Orbital properties of extra-solar planets are briey recalled and compared with equivalent features of stellar binaries. Similarities and dierences are discussed. Among the more than 115 extra-solar
On the Mass-Period Correlation of the Extrasolar Planets
We report on a possible correlation between the masses and periods of the extrasolar planets, manifested as a paucity of massive planets with short orbital periods. Monte Carlo simulations show the
Chaotic variations in the eccentricity of the planet orbiting 16 Cygni B
The planet recently discovered1 orbiting the star 16 Cyg B has the largest eccentricity (e= 0.67) of any known planet. Planets that form in circumstellar disks are expected to have nearly circular
Two New Candidate Planets in Eccentric Orbits
Doppler measurements of two G-type main-sequence stars, HD 210277 and HD 168443, reveal Keplerian variations that imply the presence of companions with masses (M sin i) of 1.28 and 5.04 MJ (where MJ
Easy Come, Easy Go: Orbital Migration and the Frequency of Giant Planet Formation
We present a statistical study of the post-formation migration of giant planets in a range of initial disk conditions. For given initial conditions we model the evolution of giant planet orbits under
The Discovery of a Planetary Companion to 16 Cygni B
High-precision radial-velocity observations of the solar-type star 16 Cygni B (HR 7504, HD 186427), taken at McDonald Observatory and at Lick Observatory, have each independently discovered periodic
Orbital migration of the planetary companion of 51 Pegasi to its present location
THE recent discovery1 and confirmation2 of a possible planetary companion orbiting the solar-type star 51 Pegasi represent a breakthrough in the search for extrasolar planetary systems. Analysis of
Tidal decay of close planetary orbits
The 4.2-day orbit of the newly discovered planet around 51~Pegasi is formally unstable to tidal dissipation. However, the orbital decay time in this system is longer than the main-sequence lifetime
Statistical properties of exoplanets - I. The period distribution: Constraints for the migration scenario
Interesting emerging observational properties of the period-mass distribution of extra-solar planets are discussed. New recent detections confirm the already emphasized lack of massive planets
The High Eccentricity of the Planet Orbiting 16 Cygni B
We consider the high eccentricity, 0.63, of the newly discovered planet orbiting 16 Cyg B, using the fact that the parent star is part of a wide binary. We show that the high eccentricity of the
