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,…
CHARA/Silmaril Instrument Software and Data Reduction Pipeline: Characterization of the Instrument in the Lab and On-Sky
Narsireddy Anugu, Theo A. ten brummelaar, Cyprien Lanthermann +9
The newly installed Silmaril beam combiner at the CHARA array is designed to observe previously inaccessible faint targets, including Active Galactic Nuclei and T-Tauri Young Stell…
Design of the new CHARA instrument SILMARIL: pushing the sensitivity of a 3-beam combiner in the H- and K-bands
Cyprien Lanthermann, Theo ten Brummelaar, Peter Tuthill +5
Optical interferometry is a powerful technique to achieve high angular resolution. However, its main issue is its lack of sensitivity, compared to other observation techniques. Eff…
CHARA/MIRC-X -- a high-sensitive six telescope interferometric imager concept, commissioning, and early science
Narsireddy Anugu, Jean-Baptiste Le Bouquin, John D. Monnier +14
MIRC-X is a six telescope beam combiner at the CHARA array that works in J and H wavelength bands and provides an angular resolution equivalent to a =331m diameter telescope. Th…
MARVEL, a four-telescope array for high-precision radial-velocity monitoring
Gert Raskin, Christian Schwab, Bart Vandenbussche +23
Since the first discovery of a planet outside of our Solar System in 1995, exoplanet research has shifted from detecting to characterizing worlds around other stars. The TESS (NASA…
Optimizing MARVEL for the radial velocity follow-up of TESS and PLATO transiting exoplanets
Cyprien Lanthermann, Joris De Ridder, Hugues Sana +6
The space missions TESS and PLATO plan to double the number of 4000 exoplanets already discovered and will measure the size of thousands of exoplanets around the brightest stars in…
A New Frontier for J-band Interferometry: Dual-band NIRInterferometry with MIRC-X
Aaron Labdon, John D. Monnier, Stefan Kraus +11
In this contribution we report on our work to increase the spectral range of the Michigan Infrared Combiner-eXeter (MIRC-X) instrument at the CHARA array to allow for dual H and J…
MIRC-X: a highly-sensitive six telescope interferometric imager at the CHARA Array
Narsireddy Anugu, Jean-Baptiste Le Bouquin, John D. Monnier +11
MIRC-X (Michigan InfraRed Combiner-eXeter) is a new highly-sensitive six-telescope interferometric imager installed at the CHARA Array that provides an angular resolution equivalen…
Modeling the e-APD SAPHIRA/C-RED ONE camera at low flux level: an attempt of photon counting in the near-infrared with the MIRC-X interferometric combiner
C. Lanthermann, N. Anugu, J. -B. Le Bouquin +3
We implement an electron avalanche photodiode (e-APD) in the MIRC-X instrument, upgrade of the 6-telescope near-infrared imager MIRC, at the CHARA array. This technology should imp…
MYSTIC: Michigan Young STar Imager at CHARA
John D. Monnier, Jean-Baptiste Le Bouquin, Narsireddy Anugu +6
We present the design for MYSTIC, the Michigan Young STar Imager at CHARA. MYSTIC will be a K-band, cryogenic, 6-beam combiner for the Georgia State University CHARA telescope arra…
Astronomical interferometry with near-IR e-APD at CHARA: characterization, optimization and on-sky operation
Cyprien Lanthermann, Jean-Baptiste Le Bouquin, Narsireddy Anugu +2
We characterize a near-infrared C-RED ONE camera from First Light Imaging (FLI). This camera uses a SAPHIRA electron avalanche photo-diode array (e-APD) from Leonardo (previously S…
MIRC-X/CHARA: sensitivity improvements with an ultra-low noise SAPHIRA detector
Narsireddy Anugu, Jean-Baptiste Le Bouquin, John D. Monnier +9
MIRC-X is an upgrade of the six-telescope infrared beam combiner at the CHARA telescope array, the world's largest baseline interferometer in the optical/infrared, located at the M…
The MIRC-X 6-telescope imager: Key science drivers, instrument design and operation
Stefan Kraus, John D. Monnier, Narsireddy Anugu +7
MIRC-X is a new beam combination instrument at the CHARA array that enables 6-telescope interferometric imaging on object classes that until now have been out of reach for milliarc…
