Self-calibration of adaptive optics systems. Application to the THEMIS solar telescope
Clementine Bechet, Eric Thiebaut, Michel Tallon +3
The interaction matrix models the effects of deformable mirror (DM) commands as perceived by the wavefront sensor (WFS) and is the cornerstone of the Adaptive Optics (AO) control.…
Upgrading SPHERE with the second stage AO system SAXO+: non-common path aberrations estimation and correction
Johan Mazoyer, Charles Goulas, Fabrice Vidal +16
SAXO+ is a planned enhancement of the existing SAXO, the VLT/ SPHERE adaptive optics system, deployed on ESO's Very Large Telescope. This upgrade is designed to significantly enhan…
Closing the loop as an inverse problem: the real-time control of THEMIS adaptive optics
Éric Thiébaut, Michel Tallon, Isabelle Tallon-Bosc +4
We have taken advantage of the implementation of an adaptive optics system on the Themis solar telescope to implement innovative strategies based on an inverse problem formulation…
Optically thin circumstellar medium in Lyr A system
M. Brož, D. Mourard, J. Budaj +7
beta Lyr A is a complex binary system with an extensive observational dataset: light curves (from FUV to FIR), interferometric squared visibility, closure phase, triple product mea…
Precise calibration of the dependence of surface brightness-colour relations on colour and class for late-type stars
A. Salsi, N. Nardetto, D. Mourard +9
Surface brightness-colour relations (SBCRs) are used to derive the stellar angular diameters from photometric observations. They have various astrophysical applications, such as th…
Calibrating the surface brightness - color relation for late-type red giants stars in the visible domain using VEGA/CHARA interferometric observations
N. Nardetto, A. Salsi, D. Mourard +14
The surface brightness - color relationship (SBCR) is a poweful tool for determining the angular diameter of stars from photometry. It was for instance used to derive the distance…
