Visual Orbits of Wolf-Rayet Stars II: The Orbit of the Nitrogen-Rich WR Binary WR 138 measured with the CHARA Array
Amanda Holdsworth, Noel Richardson, Gail H. Schaefer +19
Classical Wolf-Rayet stars are descendants of massive OB-type stars that have lost their hydrogen-rich envelopes, and are in the final stages of stellar evolution, possibly explodi…
Visual Orbits of Wolf-Rayet Stars I: The Orbit of the dust-producing Wolf-Rayet binary WR\,137 measured with the CHARA Array
Noel D. Richardson, Gail H. Schaefer, Jan J. Eldridge +19
Classical Wolf-Rayet stars are the descendants of massive OB stars that have lost their hydrogen envelopes and are burning helium in their cores prior to exploding as type Ib/c sup…
Open loop calibration and closed loop non-perturbative estimation of the lateral errors of an adaptive optics system: examples with GRAVITY+ and CHARA experimental data
Anthony Berdeu, Henri Bonnet, Jean-Baptiste Le Bouquin +15
Performances of an adaptive optics (AO) system are directly linked with the quality of its alignment. During the instrument calibration, having open loop fast tools with a large ca…
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…
Recent and Upcoming Upgrades for MIRC-X and MYSTIC on the CHARA Array
Noura Ibrahim, Mayra Gutierrez, John D. Monnier +17
MIRC-X and MYSTIC are six-telescope near-infrared beam (1.08-2.38 m) combiners at the CHARA Array on Mt Wilson CA, USA. Ever since the commissioning of MIRC-X (J and H bands) in…
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…
CHARA/Silmaril Instrument Software and Data Reduction Pipeline: Characterization of the Instrument in the Lab and On-Sky
Narsireddy Anugu, Theo A. ten brummelaar, Cyprien Lanthermann +9
The newly installed Silmaril beam combiner at the CHARA array is designed to observe previously inaccessible faint targets, including Active Galactic Nuclei and T-Tauri Young Stell…
The Orbit and Mass of the Cepheid AW Per
Nancy Remage Evans, Alexandre Gallenne, Pierre Kervella +17
The Cepheid AW Per is a component in a multiple system with a long period orbit. The radial velocities of Griffin (2016) cover the 38 year orbit well. An extensive program of inter…
