The dusty circumstellar environment of Betelgeuse during the Great Dimming as seen by VLTI/MATISSE
E. Cannon, M. Montargès, A. de Koter +23
The 'Great Dimming' of the prototypical red supergiant Betelgeuse, which occurred between December 2019 and April 2020, gives us unprecedented insight into the processes occurring…
Redshift Evolution of the Feedback / Cooling Equilibrium in the Core of 48 SPT Galaxy Clusters: A Joint -SPT-ATCA analysis
F. Ruppin, M. McDonald, J. Hlavacek-Larrondo +17
We analyze the cooling and feedback properties of 48 galaxy clusters at redshifts selected from the South Pole Telescope (SPT) catalogs to evolve like the progenito…
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…
Astro2020 Science White Paper: High Angular Resolution Astrophysics - Fundamental Stellar Parameters
Gerard van Belle, Ellyn Baines, Tabetha Boyajian +8
Direct determination of fundamental stellar parameters has many profound and wide-ranging impacts throughout astrophysics. These determinations are rooted in high angular resolutio…
Precision Analysis of Evolved Stars
Stephen Ridgway, Rachel Akeson, Ellyn Baines +20
Evolved stars dominate galactic spectra, enrich the galactic medium, expand to change their planetary systems, eject winds of a complex nature, produce spectacular nebulae and illu…
Stellar atmospheres, atmospheric extension and fundamental parameters: weighing stars using the stellar mass index
Hilding R. Neilson, Fabien Baron, Ryan Norris +2
One of the great challenges in understanding stars is measuring their masses. The best methods for measuring stellar masses include binary interaction, asteroseismology and stellar…
The Multiplicity of Massive Stars: A High Angular Resolution Survey with the HST Fine Guidance Sensor
E. J. Aldoretta, S. M. Caballero-Nieves, D. R. Gies +11
We present the results of an all-sky survey made with the Fine Guidance Sensor on Hubble Space Telescope to search for angularly resolved binary systems among the massive stars. Th…
The Mass of the Central Black Hole in the Nearby Seyfert Galaxy NGC5273
Misty C. Bentz, Daniel Horenstein, Craig Bazhaw +9
We present the results of a reverberation-mapping program targeting NGC5273, a nearby early-type galaxy with a broad-lined active galactic nucleus. Over the course of the monitorin…
Comparative Modelling of the Spectra of Cool Giants
T. Lebzelter, U. Heiter, C. Abia +24
Our ability to extract information from the spectra of stars depends on reliable models of stellar atmospheres and appropriate techniques for spectral synthesis. Various model code…
