Coronography with adaptive optics: the ADONIS coronograph
نویسندگان
چکیده
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 paper the design and performance analysis of the ADONIS coronograph, discuss the observing and data reduction strategy, and illustrate its application to a few astrophysical programmes.

High Angular Resolution Coronography for Adaptive Optics 1
Recent adaptive optics systems in astronomy achieve high-angular resolution. With the extreme stability of the images, detection at very low uxes can be reached using a coronograph at the diiraction limit of the telescopes. This paper is an overview of the issues of stellar coronography used at the diiraction limit. Image formation through such a system is illustrated by numerical simulations. ...
متن کاملA stellar coronograph for the COME - ON - PLUS adaptive optics system ?
We present here the first scientific results obtained with the coronograph described by Beuzit et al. (1996, hereafter paper I), developed to be used together with the come-on-plus/adonis adaptive optics (AO) system. Two IRAS excess Main Sequence (MS) stars, namely HR 4796 and HR 2020 (β Pictoris), have been observed. No circumstellar disk is detected around HR 4796, down to 2′′ from the star. ...
متن کاملActive Optics and Coronography with the Hubble Space Telescope
In the eld of planet and proto-planetary disk detection, achieving high angular resolution and high dynamic range is a necessity. Ground images are blurred by atmospheric turbulence and therefore adaptive optics is necessary to achieve sub-arcsecond images. Coronography coupled with adaptive optics on ground-based telescopes is a way to get both good spatial resolution and high dynamic range. H...
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 کاملThe mass ratio distribution of B - type visual binaries in the Sco OB 2 association ? , ? ?
The sample of 115 B-type stars in Sco OB2 association is examined for existence of visual companions with ADONIS near-infrared adaptive optics system and coronograph in J and Ks bands. Practically all components in the separation range 0. ′′3–6. ′′4 (45 − 900 A.U.) were detected, with magnitudes down to K = 16. The K and J−K photometry of primaries and differential photometry and astrometry of ...
