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…
Near-infrared flares from accreting gas around the supermassive black hole at the Galactic Centre
R. Genzel, R. Schoedel, T. Ott +5
Recent measurements of stellar orbits provide compelling evidence that the compact radio source Sagittarius A* at the Galactic Centre is a 3.6-million-solar-mass black hole. Sgr A*…
The Stellar Cusp Around the Supermassive Black Hole in the Galactic Center
R. Genzel, R. Schoedel, T. Ott +12
We analyze deep near-IR adaptive optics imaging as well as new proper motion data of the nuclear star cluster of the Milky Way. The surface density distribution of faint stars peak…
Exoplanet detection capability of the COROT space mission
P. Borde, D. Rouan, A. Leger
COROT will be the first high precision photometric satellite to be launched with the aim of detecting exoplanets by the transit method. In this paper, we present the simulations we…
VLT/NACO adaptive optics imaging of the TY CrA system - A fourth stellar component candidate detected
G. Chauvin, A-M. Lagrange, H. Beust +11
We report the detection of a possible subsolar mass companion to the triple young system TY CrA using the NACO instrument at the VLT UT4 during its commissioning. Assuming for TY C…
Inward Bound: Studying the Galactic Centre with NAOS/CONICA
T. Ott, R. Schoedel, R. Genzel +25
We report on the first results obtained using adaptive optics measurements of the Galactic Centre done with NAOS/CONICA.
Rationale for the use of color information on Eddington
P. Borde, A. Leger, D. Rouan +1
For the Eddington mission, the intrinsic stellar variability can be a major source of noise in the detection of extrasolar planets by the transit method. We derive that most detect…
