Abstract We obtained low resolution (R=100) mid-infrared (8–13 μm wavelengths) spectra of 8 nearby young main sequence stars with the Keck 1 telescope and Long-Wavelength Spectrometer (LWS) to search for 10 μm silicate (Si–O stretch) emission from circumstellar dust. No stars exhibited readily apparent emission: Spectra were then analyzed by least-squares fitting of a template based on a spectrum of Comet Hale-Bopp. Using this technique, we were able to constrain the level of silicate emission… Expand
Ten Micron Observations of Nearby Young Stars
We present new 10 μm photometry of 21 nearby young stars obtained at the Palomar 5 m and at the Keck I 10 m telescopes as part of a program to search for dust in the habitable zone of young stars.Expand
Detection of the inner-debris disk of Vega with CHARA/FLUOR
Using the FLUOR beam-combiner installed at the CHARA Array (Mt. Wilson, CA), we have obtained highprecision visibility measurements of Vega, one of the prototypic debris-disk stars, known to beExpand
Circumstellar material in the Vega inner system revealed by CHARA/FLUOR
Context. Only a handful of debris disks have been imaged up to now. Due to the need for high dynamic range and high angular resolution, very little is known about the inner planetary region, whereExpand
Hot exozodiacal dust resolved around Vega with IOTA/IONIC
Context. Although debris discs have been detected around a significant number of main-sequence stars, only a few of them are known to harbour hot dust in their inner part where terrestrial planetsExpand
Where Are the M Dwarf Disks Older Than 10 Million Years
We present 11.7 μm observations of nine late-type dwarfs obtained at the Keck I 10 m telescope in 2002 December and 2003 April. Our targets were selected for their youth or apparent IRAS 12 μmExpand
The Nearest Young Moving Groups
The latest results in the research of forming planetary systems have led several authors to compile a sample of candidates for searching for planets in the vicinity of the Sun. Young stellarExpand

8-13 Micron Spectroscopy of Young Stars
We present 8-13 μm spectra of 23 young stars acquired with the UKIRT CGS3 spectrometer, including T Tauri, Herbig Ae/Be, and FU Orionis stars. Silicate emission and absorption features can generallyExpand
Thermal Infrared Imaging and Spectroscopy of Comet Hale-Bopp (C/1995 O1)
We present λ = 3-5 and 8-13 μm images and long-slit spectra of comet Hale-Bopp (C/1995 O1) taken in 1997 February-April, near the time of perihelion passage. In agreement with other infraredExpand
Detection of silicates in the 51 Ophiuchi system
We have detected a prominent 10 μm silicate emission feature in 51 Oph, a B9.5 Ve star with circumstellar emission. 51 Oph shows the Vega phenomenon, probable disk emission from a main-sequence star.Expand
Observational Constraints on Late Heavy Bombardment Episodes around Young Solar Analogs
Thermal emission from dust is investigated around 36 nearby G and K stars selected as analogs to the young Sun during the period of late heavy bombardment on the Moon (prior to 3.8 Ga). MeasurementsExpand
A 25 micron search for Vega-like disks around main-sequence stars with ISO
We present an ISO 25 m photometric survey of a sample of 81 nearby main-sequence stars in order to determine the incidence of \warm" dust disks. All stars were detected by ISO. We used an empiricalExpand
Incidence and survival of remnant disks around main-sequence stars
We present photometric ISO 60 and 170 um measurements, complemented by some IRAS data at 60 ${\mu\textrm{m}}$, of a sample of 84 nearby main-sequence stars of spectral class A, F, G and K in order toExpand
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 observationsExpand

Near-infrared (2.2 μm) long baseline interferometric observations of Vega are presented. The stellar disk of the star has been resolved, and the data have been fitted with a limb-darkened stellarExpand
DISCOVERY OF A SHELL AROUND ALPHA-LYRAE
IRAS observations of Alpha Lyrae reveal a large infrared excess beyond 12 microns. The excess over an extrapolation of a 10,000 K blackbody is a factor of 1.3 at 25 microns, 7 at 60 microns, and 16Expand
