On the interferometric sizes of young stellar objects
Long-baseline optical interferometers can now detect and resolve hot dust emission thought to arise at the inner edge of circumstellar disks around young stellar objects (YSOs). We argue that theExpand
High-resolution imaging of dust shells by using Keck aperture masking and the IOTA interferometer
We present first results of an experiment to combine data from Keck aperture masking and the Infrared-Optical Telescope Array to image the circumstellar environments of evolved stars with ~20 masExpand
Imaging the Surface of Altair
Using optical long-baseline interferometry, a near-infrared image of the rapidly rotating hot star Altair is constructed with a resolution of <1 milliarcsecond that clearly reveals the strong effect of gravity darkening on the highly distorted stellar photosphere. Expand
Unveiling Mira stars behind the molecules - Confirmation of the molecular layer model with narrow band near-infrared interferometry
We have observed Mira stars with the FLUOR beamcombiner on the IOTA interferometer in narrow bands around $2.2\,\mu$m wavelength. We find systematically larger diameters in bands contaminated byExpand
Spatially Resolved Circumstellar Structure of Herbig Ae/Be Stars in the Near-Infrared
We have conducted the first systematic study of Herbig Ae/Be stars using the technique of long baseline stellar interferometry in the near-infrared, with the objective of characterizing theExpand
Keck Interferometer Observations of Classical and Weak-line T Tauri Stars
We present observations of the T Tauri stars BP Tau, DG Tau, DI Tau, GM Aur, LkCa 15, RW Aur, and V830 Tau, using long baseline infrared interferometry at K band (2.2 μm) from the KeckExpand
Few Skewed Disks Found in First Closure-Phase Survey of Herbig Ae/Be Stars
Using the three-telescope IOTA interferometer on Mount Hopkins, we report results from the first near-infrared (lambda = 1.65 mu m) closure-phase survey of young stellar objects (YSOs). These closureExpand
New insights on the AU-scale circumstellar structure of FU Orionis
We report new near-infrared, long-baseline interferometric observations at the AU scale of the pre-main-sequence star FU Orionis with the PTI, IOTA and VLTI interferometers. This young stellar objectExpand
Visual/infrared interferometry of Orion Trapezium stars: preliminary dynamical orbit and aperture synthesis imaging of the θ1 Orionis C system
Context. Located in the Orion Trapezium cluster, θ^1 Ori C is one of the youngest and nearest high-mass stars (O5-O7) known. Besides its unique properties as a magnetic rotator, the system is alsoExpand
PIONIER: a 4-telescope visitor instrument at VLTI
PIONIER stands for Precision Integrated-Optics Near-infrared Imaging ExpeRiment. It combines four 1.8m Auxilliary Telescopes or four 8m Unit Telescopes of the Very Large Telescope InterferometerExpand
