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…
The Orbit and Dynamical Mass of Polaris: Observations with the CHARA Array
Nancy Remage Evans, Gail Schaefer, Alexandre Gallenne +19
The 30 year orbit of the Cepheid Polaris has been followed with observations by the CHARA Array (Center for High Angular Resolution Astronomy) from 2016 through 2021. An additional…
High spectral-resolution interferometry down to 1 micron with Asgard/BIFROST at VLTI: Science drivers and project overview
Stefan Kraus, Daniel Mortimer, Sorabh Chhabra +10
We present science cases and instrument design considerations for the BIFROST instrument that will open the short-wavelength (Y/J/H-band), high spectral dispersion (up to R=25,000)…
