Which isoplanatic patch size for high angular resolution techniques? [PDF]

Adaptive Optics Systems VII, 2020
The isoplanatic patch size is of interest to reach a high performance with an Adaptive Optics system, since the reference star for its calibration should be located in the same isoplanatic domain than the science source. Different techniques and methods have been developed leading to estimations of the isoplanatic patch but all are model-dependent.

On the isoplanatic patch size in High Angular Resolution Techniques [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
To reach a high performance with an adaptive optics system, we need a calibration using a reference source. This latter should be located in the same isoplanatic domain as the science source. Different techniques and methods have been developed leading to estimations of the isoplanatic patch but all are model-dependent. We developed a new technique for

Formation and evolution of planetary systems: the impact of high-angular resolution optical techniques [PDF]

The Astronomy and Astrophysics Review, 2009
The direct images of giant extrasolar planets recently obtained around several main sequence stars represent a major step in the study of planetary systems. These high-dynamic range images are among the most striking results obtained by the current generation of high angular resolution instruments, which will be superseded by a new generation of ...

The wide-field imaging interferometry testbed: enabling techniques for high angular resolution astronomy [PDF]

SPIE Proceedings, 2007
The Wide-Field Imaging Interferometry Testbed (WIIT) was designed to develop techniques for wide-field of view imaging interferometry, using "double-Fourier" methods. These techniques will be important for a wide range of future space-based interferometry missions.

Study of the dynamical and morphological properties of massive stars with high angular resolution techniques

, 2015
Sin embargo esas estructuras han sido elusivas para los objetos más masivos. En este capítulo se presenta el estudio del objeto masivo: NGC 3603 IRS 9A con la cámara infrarroja de alta resolución angular NACO del Very Large Telescope (VLT). Dichas observaciones se realizaron en el modo interferométrico de NACO, a través de la técnica conocida como ...
