CHARA Array adaptive optics: complex operational software and performance
Narsireddy Anugu, Theo ten Brummelaar, Nils H. Turner +18
The CHARA Array is the longest baseline optical interferometer in the world. Operated with natural seeing, it has delivered landmark sub-milliarcsecond results in the areas of stel…
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…
ARMADA I: Triple Companions Detected in B-Type Binaries alpha Del and nu Gem
Tyler Gardner, John D. Monnier, Francis C. Fekel +19
Ground-based optical long-baseline interferometry has the power to measure the orbits of close binary systems at ~10 micro-arcsecond precision. This precision makes it possible to…
The inner disk of RY Tau: evidence of stellar occultation by the disk atmosphere at the sublimation rim from K-band continuum interferometry
Claire L. Davies, Stefan Kraus, Tim J. Harries +13
We present models of the inner region of the circumstellar disk of RY Tau which aim to explain our near-infrared (-band: m) interferometric observations while remaining…
