A catalog of reference stars for long baseline stellar interferometry
Pascal Borde, Vincent Coude du Foresto, Gilles Chagnon +1
The calibration process of long baseline stellar interferometers requires the use of reference stars with accurately determined angular diameters. We present a catalog of 374 caref…
10 um wavefront spatial filtering: first results with chalcogenide fibers
Pascal Borde, Guy Perrin, Thanh Nguyen +5
Wavefront cleaning by single-mode fibers has proved to be efficient in optical-infrared interferometry to improve calibration quality. For instance, the FLUOR instrument has demons…
Speckle nulling with space-based coronagraphs
Pascal Borde, Wesley Traub
Following the tracks of Malbet, Yu, & Shao (1995} on dark hole algorithms, we present analytical methods to measure and correct the speckle noise behind an ideal coronagraph. We sh…
Towards multi-dimensional analysis of transmission spectroscopy. Part II: Day-night induced biases in retrievals from hot to ultra-hot Jupiters
William Pluriel, Jeremy Leconte, Vivien Parmentier +4
Hot Jupiters are very good targets for transmission spectroscopy analysis. Their atmospheres have a large scale height implying a high signal to noise ratio. As these planets orbit…
On the Mass of CoRoT-7b
Artie P. Hatzes, Malcolm Fridlund, Gil Nachmani +25
The mass of CoRoT-7b, the first transiting superearth exoplanet, is still a subject of debate. A wide range of masses have been reported in the literature ranging from as high as 8…
The SARS algorithm: detrending CoRoT light curves with Sysrem using simultaneous external parameters
Aviv Ofir, Roi Alonso, Aldo Stefano Bonomo +31
Surveys for exoplanetary transits are usually limited not by photon noise but rather by the amount of red noise in their data. In particular, although the CoRoT spacebased survey d…
