Coronography with adaptive optics: the ADONIS coronograph
The combination of adaptive optics and coronographic techniques providing at the same time high angular resolution and high dynamic range is a powerful tool to study the close environment of bright objects in different fields of astrophysics (search for brown dwarfs and giant extra-solar planets around nearby stars, search for circumstellar disks, study of AGB outflows, etc). We present in this...
متن کاملMulti-Agent control system for the ADONIS adaptive optics instrument
ADONIS is a complex but user-friendly adaptive optics (AO) instrument for the European Southern Observatory 3.6-m telescope. ADONIS is composed of several interacting parts, including the astronomer. Multiple parameters innuence the system performance and they are diicult to handle by the astronomer. A multi-agent, distributed, and message oriented control system is designed. The communication ...
متن کاملNew cardenolides from the seeds of Adonis aestivalis.
Chemical investigation of the seeds of Adonis aestivalis has led to the isolation of a new cardenolide (3β,5α,14β,17β-tetrahydroxycard-20,22-enolide) (1), two new glycosides (2, 3) of 1, and a new strophanthidin hexaglycoside (4), together with a known compound, strophanthidin 3-O-β-D-glucopyranoside (5). The structures of 1-4 were determined by 1D- and 2D-NMR spectroscopic analysis and the res...
متن کاملASTROPHYSICS ADONIS observations of the HD 100546 circumstellar dust disk ⋆
We report in this letter the first resolved images of the circumstellar dust disk around the Pre-Main-Sequence star HD 100546. These near-infrared images were obtained in J and short K bands with the adap-tive optics system ADONIS at the ESO observatory. A bright disk extending 2 arcsec (200 AU) far from the star and viewed with an inclination with respect to the line of sight around 50 degrees...
متن کاملAutomated Diagnosis Through Ontologies and Logical Descriptions: The ADONIS Approach
The combination of the burgeoning interest in efficient and reliable Health Systems and the advent of the Information Age represent both a challenge and an opportunity for new paradigms and cutting-edge technologies reaching a certain degree of maturity. Hence, the use of Semantic Technologies for Automated Diagnosis could leverage the potential of current solutions by providing inference-based...
