CHARA Array Observations of the Evolved Components in Symbiotic Star Systems
Thomas Martin Gaudin, Ryan Norris, Magdalena Otulakowska-Hypka +30
The nature of the mechanisms that drive mass transfer in symbiotic stars remains an area of active research in stellar astronomy. Constraining the role that both stellar winds and…
Pre-nova Observations of T CrB: A view from the CHARA Array
Ryan Norris, Narsireddy Anugu, Thomas Gaudin +38
T CrB is a symbiotic recurrent nova consisting of a red giant and white dwarf with recent eruptions in 1866 and 1946 and an anticipated eruption in the mid 2020s. We report CHARA A…
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…
Long Term Evolution of Surface Features on the Red Supergiant AZ Cyg
Ryan P. Norris, Fabien R. Baron, John D. Monnier +23
We present H-band interferometric observations of the red supergiant (RSG) AZ Cyg made with the Michigan Infra-Red Combiner (MIRC) at the six-telescope Center for High Angular Reso…
Visual Orbits of Spectroscopic Binaries with the CHARA Array. II. The eclipsing binary HD 185912
Kathryn V. Lester, Douglas R. Gies, Gail H. Schaefer +8
We present the visual orbit of the double-lined eclipsing binary, HD 185912, from long baseline interferometry with the CHARA Array. We also obtain echelle spectra from the Apache…
Visual Orbits of Spectroscopic Binaries with the CHARA Array. I. HD 224355
Kathryn V. Lester, Douglas R. Gies, Gail H. Schaefer +5
We present the visual orbit of the double-lined spectroscopic binary HD 224355 from interferometric observations with the CHARA Array, as well as an updated spectroscopic analysis…
