Optical Images of an Exosolar Planet 25 Light-Years from Earth
Optical observations of an exoplanet candidate, Fomalhaut b, show that the planet's mass is at most three times that of Jupiter; a higher mass would lead to gravitational disruption of the belt, matching predictions of its location.
A planetary system as the origin of structure in Fomalhaut's dust belt
The sharp inner edge and offset demonstrate the presence of planetary-mass objects orbiting Fomalhaut, demonstrating the structure of a dusty disk modified by the gravitational influence of planets.
The Gemini Deep Planet Survey
We present the results of the Gemini Deep Planet Survey, a near-infrared adaptive optics search for giant planets and brown dwarfs around 85 nearby young stars. The observations were obtained with…
FOMALHAUT'S DEBRIS DISK AND PLANET: CONSTRAINING THE MASS OF FOMALHAUT B FROM DISK MORPHOLOGY
Following the optical imaging of exoplanet candidate Fomalhaut b (Fom b), we present a numerical model of how Fomalhaut's debris disk is gravitationally shaped by a single interior planet. The model…

Observations ofBeta Pictoris clearly detect the planet, Beta Pictoris b, in a single 60-s exposure with minimal postprocessing, and fitting the Keplerian orbit of Beta Pic b using the new position together with previous astrometry gives a factor of 3 improvement in most parameters over previous solutions.
Discovery of a Large Dust Disk Around the Nearby Star AU Microscopii
The discovery of a circumstellar dust disk surrounding AU Microscopii, a young M star at 10 parsec has the same age and origin as β Pictoris, another nearby star surrounded by a dust disk, providing new clues on how the majority of planetary systems might form and evolve.

Discovery and spectroscopy of the young jovian planet 51 Eri b with the Gemini Planet Imager
Using the Gemini Planet Imager, a Jupiter-like planet is discovered orbiting the ~20-million-year-old star 51 Eridani at a projected separation of 13 astronomical units and has a methane signature and is probably the smallest exoplanet that has been directly imaged.
A Submillimeter Search of Nearby Young Stars for Cold Dust: Discovery of Debris Disks around Two Low-Mass Stars
We present results from a James Clerk Maxwell Telescope/SCUBA 850 μm search for cold dust around eight nearby young stars belonging to the β Pic (t ≈ 12 Myr) and the Local Association (t ≈ 50 Myr)…
