The infrared L'-band view of the Galactic Center with NAOS-CONICA at VLT

Y. Clénet, D. Rouan, E. Gendron +9

We report on Galactic Center L'-band observations made during NAOS/CONICA Science Verification. Colors of the inner 2" stars reveal an infrared excess of S2, the closest star to th…

Hot Very Small dust Grains in NGC 1068 seen in jet induced structures thanks to VLT/NACO adaptive optics

Daniel Rouan, Francois Lacombe, Eric Gendron +12

We present K, L and M diffraction-limited images of NGC 1068 obtained with NAOS+CONICA at VLT/YEPUN over a 3.5" field around the central engine. Hot dust (Tcol = 550-650 K) is foun…

VLT/NACO infrared adaptive optics images of small scale structures in OMC1

Francois Lacombe, Eric Gendron, Daniel Rouan +10

Near-infrared observations of line emission from excited H2 and in the continuum are reported in the direction of the Orion molecular cloud OMC1, using the European Southern Observ…

NACO Polarimetric Differential Imaging of TW Hya: A Sharp Look at the Closest T Tauri Disk

D. Apai, I. Pascucci, W. Brandner +5

We present high-contrast imaging data on the disk of the classical T Tauri star TW Hya. The images were obtained through the polarimetric differential imaging technique with the ad…

Direct measurement of the size and shape of the present-day stellar wind of Eta Carinae

R. van Boekel, P. Kervella, M. Schoeller +7

We present new high angular resolution observations at near-IR wavelengths of the core of the Luminous Blue Variable Eta Carinae, using NAOS-CONICA at the VLT and VINCI at the VLT…
