We present the results of a coronagraphic imaging search for extrasolar planets around the young main-sequence stars Eri and Vega. Concentrating the stellar light into the core of the point-spread function by the adaptive optic system and blocking the core by the occulting mask in the coronagraph, we have achieved the highest sensitivity for point sources in close vicinity of the both central stars. Nonetheless, we had no secure detection of a point source around the stars. The observations… 
Deep L'- and M-band Imaging for Planets around Vega and Eridani
We have obtained deep adaptive optics (AO) images of Vega and Eri to search for planetary mass companions. We observed at the MMT in the L' (3.8 μm) and M (4.8 μm) bands using Clio, a recently
Temporal Evolution of Coronagraphic Dynamic Range and Constraints on Companions to Vega
The major obstacle to the direct detection of companions to nearby stars is the overwhelming brightness of the host star. Current instruments employing the combination of adaptive optics (AO) and
Fomalhaut and Eridani are two young, nearby stars that possess extended debris disks whose structures suggest the presence of perturbing planetary objects. With its high sensitivity and stable
The cold origin of the warm dust around ε Eridani
Context. The nearby K2 V star e Eridani hosts one known inner planet, an outer Kuiper belt analog, and an inner disk of warm dust. Spitzer/IRS measurements indicate that the warm dust is present at
Imaging Extrasolar Giant Planets
High-contrast adaptive optics imaging is a powerful technique to probe the architectures of planetary systems from the outside-in and survey the atmospheres of self-luminous giant planets. Direct
Vega's hot dust from icy planetesimals scattered inwards by an outward-migrating planetary system
Vega has been shown to host multiple dust populations, including both hot exo-zodiacal dust at sub-AU radii and a cold debris disk extending beyond 100 AU. We use dynamical simulations to show how
We report on high contrast near-infrared (~2.2 μm) observations of Vega obtained with the Palomar Fiber Nuller, a dual sub-aperture rotating coronagraph installed at the Palomar Hale telescope. The
Detection of Extrasolar Planets and Circumstellar Disks
In this chapter, various observational methods of searching for extrasolar planets and circumstellar disks are reviewed. These include Doppler-shift measurements, transit detection, astrometry,
Debris disks: seeing dust, thinking of planetesimals and planets
Debris disks are optically thin, almost gas-free dusty disks observed around a significant fraction of main-sequence stars older than about 10 Myr. Since the circumstellar dust is short-lived, the
We have designed and built the first band-limited coronagraphic mask used for ground-based high-contrast imaging observations. The mask resides in the focal plane of the near-infrared camera PHARO at


Structure in the Dusty Debris around Vega
We present images of the Vega system obtained with the IRAM Plateau de Bure interferometer at a 1.3 mm wavelength with submillijansky sensitivity and ~25 resolution (about 20 AU). These observations
Deep Keck Adaptive Optics Searches for Extrasolar Planets in the Dust of Eridani and Vega
A significant population of nearby stars have strong far-infrared excesses, now known to be due to circumstellar dust in regions analogous to the Kuiper Belt of our solar system, although orders of
Structure in the Eridani Dusty Disk Caused by Mean Motion Resonances with a 0.3 Eccentricity Planet at Periastron
The morphology of the Eridani dust ring is reproduced by a numerical simulation of dust particles captured into the 5 : 3 and 3 : 2 exterior mean motion resonances with a 0.3 eccentricity 10-4 M☉
A Dust Ring around epsilon Eridani: Analog to the Young Solar System
Dust emission around the nearby star Eridani has been imaged using a new submillimeter camera (the Submillimetre Common-User Bolometer Array at the James Clerk Maxwell Telescope). At an 850 μm
Submillimetre images of dusty debris around nearby stars
Indirect detections of massive — presumably Jupiter-like — planets orbiting nearby Sun-like stars have recently been reported,. Rocky, Earth-like planets are much more difficult to detect, but clues
Evolutionary models for cool brown dwarfs and extrasolar giant planets. The case of HD 209458
We present evolutionary models for cool brown dwarfs and extra-solar giant planets. The models re- produce the main trends of observed methane dwarfs in near-IR color-magnitude diagrams. We also

The STIS CCD camera on the Hubble Space Telescope (HST) was used to take deep optical images near the K2 V main-sequence starEridani in an attempt to find an optical counterpart of the dust ring
Adaptive Optics Observations of Vega: Eight Detected Sources and Upper Limits to Planetary‐Mass Companions
From adaptive optics observations with the Palomar 5 m telescope we place upper limits on the masses of any planetary companions located between ~30 and 230 AU away from Vega, where our data are
Evidence for a Long-Period Planet Orbiting ∊ Eridani
High-precision radial velocity (RV) measurements spanning the years 1980.8‐2000.0 are presented for the nearby (3.22 pc) K2 V star e Eri. These data, which represent a combination of six independent
Dust in the Photospheric Environment II. Effect on the Near Infrared Spectra of L and T Dwarfs
We report an attempt to interpret the spectra of L and T dwarfs with the use of the unified cloudy model (UCM). For this purpose, we extend the grid of the UCMs to cases of log g = 4.5 and 5.5. The
