On-sky demonstration of dual-field interferometry at the CHARA Array
Narsireddy Anugu, John D. Monnier, Douglas R. Gies +10
Dual-field interferometry uses a bright reference star for real-time fringe tracking, allowing a second beam combiner to record long coherent integrations on a fainter off-axis sci…

Detection and Astrometry of the Ba-Bb Subsystem in Piscium: First Dual-Field Interferometry at the CHARA Array
Narsireddy Anugu, Robert Klement, John D. Monnier +14
We present the first on-sky demonstration of dual-field interferometry at the CHARA Array and the first direct resolution of the inner Ba--Bb subsystem in the bright hierarchical t…
