The Transformative Journey of HD 93521
Douglas R. Gies, Katherine Shepard, Peter Wysocki +1
HD 93521 is a massive, rapidly rotating star that is located about 1 kpc above the Galactic disk, and the evolutionary age for its estimated mass is much less than the time-of-flig…
The Solar Neighborhood XLIX: Nine Giant Planets Orbiting Nearby K Dwarfs, and the CHIRON Spectrograph's Radial Velocity Performance
Leonardo A. Paredes, Todd J. Henry, Samuel N. Quinn +5
We report initial results of a large radial velocity survey of K dwarfs up to a distance of 50 pc from the Solar System, to look for stellar, brown dwarf, and jovian planets using…
Outbursts and stellar properties of the classical Be star HD 6226
Noel D. Richardson, Olivier Thizy, Jon E. Bjorkman +58
The bright and understudied classical Be star HD 6226 has exhibited multiple outbursts in the last several years during which the star grew a viscous decretion disk. We analyze 659…
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…
Gem: a hierarchical triple system with an outer Be star
Robert Klement, Petr Hadrava, Thomas Rivinius +17
Time series of spectroscopic, speckle-interferometric, and optical long-baseline-interferometric observations confirm that Gem is a hierarchical triple system. It consists of a…
The Detection and Characterization of Be+sdO Binaries from HST/STIS FUV Spectroscopy
Luqian Wang, Douglas R. Gies, Geraldine J. Peters +4
The B-emission line stars are rapid rotators that were probably spun up by mass and angular momentum accretion through mass transfer in an interacting binary. Mass transfer will st…
