Size Distribution of Disks in the Trapezium Cluster
In this paper we present preliminary results on the size distribution of proto-planetary (“proplyds”) disks in the Trapezium Cluster, as measured... -
Status of Adaptive Optics Projects at ESO
This paper will review all Adaptive Optics systems already in operation or in construction at ESO. Roadmap toward the future AO systems both for the... -
Resolving the Arches Starburst Cluster in the Galactic Center with NAOS-CONICA
With a central density of 3⋅ 105 M⊙ pc–3 and estimated total mass of 104 M⊙, the Arches cluster is one of the most massive and compact young clusters... -
Close Companions to Nearby Young Stars from Adaptive Optics Imaging on VLT and Keck
We report the results of VLT and Keck adaptive optics surveys of known members of the η Chamaeleontis, MBM 12, and TW Hydrae (TWA) associations to... -
Near-Infrared Imaging of Late Type Stars Using CIAO on the Subaru Telescope
We have manufactured a near infrared camera named coronagraphic imager with adaptive optics; CIAO mounted on the Cassegrain focus of the Subaru 8m... -
NAOS/CONICA Imaging of the Nebula Surrounding IRAS 17340–3757
During a program to discover new YSO candidates [1], we have serendipitously discovered IRAS 17340–3757 to be a hitherto unknown carbon star with... -
NGC1068: Registration with Narrow Field of View and Morphology
Several issues are inherent to adaptive optics (AO) observations, and particular to our concern is the small field of view. It is an important issue... -
Tracing the Coronal Line Region in AGN with VLT/NACO: The Very First Results
The coronal line region in AGN is an intermediate zone between the broad- and the narrow-line regions where lines with ionization potentials, IP >50... -
Infrared Excess Sources in the Galactic Center Stellar Cluster
We present results from diffraction-limited L′-band spectroscopy and H, K, and L′-band imaging of the IRS 13 region in the Galactic Center performed... -
Nuclear Dynamics and Star Formation of AGN
We are using adaptive optics on Keck and the VLT to probe the dynamics and star formation in Seyfert and QSO nuclei, obtaining spatial resolutions... -
Note on Spectroscopy with Adaptive Optics
The performance of adaptive optics (AO) systems is more often discussed in the context of imaging capability. However, it is also a powerful... -
High Order Adaptive Optics Simulation Tool for VLTs and ELTs
In order to evaluate the performances of Adaptive Optics (AO), pertinent evaluation of the error budget must be provided. This can be performed with... -
Direct Detection of Exoplanets with Future Adaptive Optics Systems
Directly imaging extrasolar planets will greatly complement the indirect methods of planet search. The next-generation adaptive-optics instruments... -
Preliminary Commissioning Results of Altair
Altair is the facility adaptive optics (AO) system of the Gemini North Telescope. It was designed and built at the National Research Council of... -
An Adaptive Optics Search for Binaries in the Orion Nebula Cluster
We report on the results of a binary survey in the outer parts of the Orion Nebula Cluster, 0.7 to 2 pc from the cluster center. The results should... -
Spatially Resolved Spectroscopy of Proto-Planetary Nebulae
We present 3 μm spectroscopy of three carbon-rich proto-planetary nebulae. Spectroscopy with high spatial resolution afforded by the Subaru adaptive... -
Coupled Adaptive Optics and Integral Field Spectroscopy of Pre-Main-Sequence Stars
We present observations done with the OASIS instrument and the PUE’O adaptive optics system at the Canada-France-Hawaii Telescope. By combining the... -
PIGS - A New Wavefront Sensor Concept for ELTs
Adaptive Optics Systems for Extremely Large Telescopes (ELT) will need new wavefront sensing concepts to deploy their full capabilities. In this... -
The Nucleus of Centaurus A with NACO
At less than 4 Mpc away, Centaurus A (NGC 5128) is the nearest massive elliptical galaxy, the nearest radio galaxy, and the nearest recent merger. It... -
Dissipative Solitons in Reaction-Diffusion Systems
A major goal of natural science is to understand the formation of spatiallyextended patterns in all kinds of physical, chemical, biological and other...
