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…
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…
Viscous Heating and Boundary Layer Accretion in the Disk of Outbursting Star FU Orionis
Aaron Labdon, Stefan Kraus, Claire L Davies +11
Context. FU Orionis is the archetypal FUor star, a subclass of young stellar object (YSO) that undergo rapid brightening events, often gaining 4-6 magnitudes on timescales of days.…
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…
Optical interferometry and Gaia measurement uncertainties reveal the physics of asymptotic giant branch stars
A. Chiavassa, K. Kravchenko, F. Millour +20
Context. Asymptotic giant branch stars are cool luminous evolved stars that are well observable across the Galaxy and populating Gaia data. They have complex stellar surface dynami…
A triple star system with a misaligned and warped circumstellar disk shaped by disk tearing
Stefan Kraus, Alexander Kreplin, Alison K. Young +29
Young stars are surrounded by a circumstellar disk of gas and dust, within which planet formation can occur. Gravitational forces in multiple star systems can disrupt the disk. The…
