Planet formation, orbital evolution and planet-star tidal interaction
We consider several processes operating during the late stages of planet formation that can affect observed orbital elements. Disk-planet interactions,

PLANET II: A Microlensing and Transit Search for Extrasolar Planets
Due to their extremely small luminosity compared to the stars they orbit, planets outside our own Solar System are extraordinarily

Planet migration
A planetary system may undergo significant radial rearrangement during the early part of its lifetime. Planet migration can come about

Planet-sized Detectors for Ultra-high Energy Neutrinos & Cosmic Rays
Extragalactic astronomy with photons ends at ~0.1 PeV, but we know there are astrophysical sources for seven more decades of

"Osiris"(HD209458b), an evaporating planet
Three transits of the planet orbiting the solar type star HD209458 were observed in the far UV at the wavelength

A direct imaging search for wide (sub)stellar companions around rad-vel planet host stars
We present an overview of our ongoing systematic search for wide (sub)stellar companions around the stars known to host rad-vel

A free-floating planet population in the Galaxy?
Most young low-mass stars are born as binary systems, and circumstellar disks have recently been observed around the individual components

A New Transiting Extrasolar Giant Planet
We have measured radial velocities of a star, OGLE-TR-56, which shows a 1.2-day transit-like light curve found photometrically by Udalski

A Planet Candidate in the Stellar Triple System HD178911
We report the detection of a low-mass companion orbiting the solar-type star HD178911B, the distant component of the stellar triple

A planet orbiting the star Gliese 86
A 4MJ planet with a 15.8day orbital period has been detected from very precise radial velocity measurements with the CORALIE

A Possible Hybrid Scenario for Gas Giant Planet Formation in Rings
The core-accretion mechanism for gas giant formation may be too slow to create all observed gas giant planets during reasonable

DID PLANET FORMATION BEGIN INSIDE PERSISTENT GASEOUS VORTICES?
We explore here the idea, reminiscent in some respect of Von Weizsacker's (1944) and Alfven's (1976) outmoded cosmogonies, that long-lived
