CHARA/SPICA: The six-telescope visible combiner and near-infrared fringe tracker for the CHARA Array
D. Mourard, P. Bério, C. Bailet +43
The suite called Stellar Parameters and Images with a Cophased Array (SPICA) has two interferometric instruments installed at the focus of the CHARA Array located at Mount Wilson,…
Simplified model(s) of the GRAVITY+ adaptive optics system(s) for performance prediction
Anthony Berdeu, Jean-Baptiste Le Bouquin, Guillaume Mella +13
In the context of the GRAVITY+ upgrade, the adaptive optics (AO) systems of the GRAVITY interferometer are undergoing a major lifting. The current CILAS deformable mirrors (DM, 90…
CHARA/SPICA: a 6-telescope visible instrument for the CHARA Array
Denis Mourard, Philippe Berio, Cyril Pannetier +25
With a possible angular resolution down to 0.1-0.2 millisecond of arc using the 330 m baselines and the access to the 600-900 nm spectral domain, the CHARA Array is ideally configu…
IMAGE-OI: an OIFITS extension and its application in OImaging to compare image reconstruction algorithms
Ferréol Soulez, Laurent Bourgès, Antoine Kaszczyc +6
In interferometry, the quality of the reconstructed image depends on the algorithm used and its parameters, and users often need to compare the results of several algorithms to dis…
Pseudomagnitudes and Differential Surface Brightness: Application to the apparent diameter of stars
Alain Chelli, Gilles Duvert, Laurent Bourgès +4
The diameter of a star is a major observable that serves to test the validity of stellar structure theories. It is also a difficult observable that is mostly obtained with indirect…
Building the 'JMMC Stellar Diameters Catalog' using SearchCal
Sylvain Lafrasse, Guillaume Mella, Daniel Bonneau +4
The JMMC Calibrator Workgroup has long developed methods to ascertain the angular diameter of stars, and provides this expertise in the SearchCal software. SearchCal dynamically fi…
