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,…

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…

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 Near-Infrared Imaging of the Yellow Hypergiant Star Cassiopeiae: Convection Cells and Circumstellar Envelope

Narsireddy Anugu, Fabien Baron, John D. Monnier +18

Massive evolved stars such as red supergiants and hypergiants are potential progenitors of Type II supernovae, and they are known for ejecting substantial amounts of matter, up to…

The dust sublimation region of the Type 1 AGN NGC4151 at a hundred micro-arcsecond scale as resolved by the CHARA Array interferometer

Makoto Kishimoto, Matt Anderson, Theo ten Brummelaar +10

The nuclear region of Type 1 AGNs has only been partially resolved so far in the near-infrared (IR) where we expect to see the dust sublimation region and the nucleus directly with…
