Adaptive optics observations of asteroid (216) Kleopatra
The large main-belt asteroid (216) Kleopatra has been for long suspected to be a binary object, mainly due to its large lightcurve amplitude. However, recent observations suggest that it is a single “bone-shaped” or bi-lobated body (Ostro et al. 2000; Tanga et al. 2001). We present results obtained from ground-based adaptive optics observations, and in agreement with the radar raw-observations,...
متن کاملHST/FGS Observations of the Asteroid (216) Kleopatra
Interferometric observations of asteroid (216) Kleopatra were performed in January 2000 using the Fine Guidance Sensors (FGS) aboard HST. The FGS data obtained clearly suggest that (216) Kleopatra is composed of two lobes in contact, in agreement with the radar data (Ostro et al. 2000, Science 288, 836–839), and provide more precise constraints on the absolute size of this peculiar object. c © ...
متن کاملFour-year observations of T Tauri with adaptive optics
We report here on a series of adaptive optics observations of T Tauri made from Dec. 1993 to Nov. 1997. Observations show an arc-like structure extending toward north and north-west. On the south side a bright tail-like structure extends radially in the south-west direction. Both structures seem to be produced by dust scattering. Close to T Tauri, the south structure forms bright clumps near a ...
متن کاملAdaptive optics observations of luminous infrared galaxies II . Imaging
We present adaptive optics observations of the Luminous Infrared Galaxy, Arp 299. This merging galaxy (NGC 3690) is the site of a very powerful starburst activity. Very high angular resolution observations at 2.2μm reveal many superclusters of newly formed stars. Those clusters feature intrinsic luminosities and surface densities well above the figures generally found in the Local Cluster, poin...
متن کاملImplications of Atmospheric Differential Refraction for Adaptive Optics Observations
Many adaptive optics systems operate by measuring the distortion of the wavefront in one wavelength range and performing the scientific observations in a second, different wavelength range. One common technique is to measure wavefront distortions at wavelengths <∼1 μm while operating the science instrument at wavelengths>∼ 1 μm. The index of refraction of air decreases sharply from shorter visi...
