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…

CHARA Array Delay Lines: Upgrades, Performance and Future Directions

Narsireddy Anugu, Nils H. Turner, Theo A. ten Brummelaar +12

Long baseline optical and infrared interferometric arrays achieve high angular resolution and enable detailed astrophysical measurements. Interferometers have enabled observations…

Time-Evolution Images of the Hypergiant RW Cephei During the Re-brightening Phase Following the Great Dimming

Narsireddy Anugu, Douglas R. Gies, Rachael M. Roettenbacher +17

Stars with initial masses larger than 8 solar masses undergo substantial mass loss through mechanisms that remain elusive. Unraveling the origins of this mass loss is important for…

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…
