Precise Age for the Binary Star System 12 Com in the Coma Berenices Cluster
Rex Lam, Eric L. Sandquist, Gail H. Schaefer +11
We present measurements of the interferometrically-resolved binary star system 12 Com and the single giant star 31 Com in the cluster Coma Berenices. 12 Com is a double-lined spect…
Gamma Cas Stars as Be + White Dwarf Binary Systems
Douglas Gies, Luqian Wang, Robert Klement
The origin of the bright and hard X-ray emission flux among the gamma Cas subgroup of B-emission line (Be) stars may be caused by gas accretion onto an orbiting white dwarf (WD) co…
The Orbits and Dynamical Masses of the Castor System
Guillermo Torres, Gail H. Schaefer, John D. Monnier +12
Castor is a system of six stars in which the two brighter objects, Castor A and B, revolve around each other every 450 yr and are both short-period spectroscopic binaries. Th…
The Interferometric Binary Epsilon Cancri in Praesepe: Precise Masses and Age
Leslie M. Morales, Eric L. Sandquist, Gail H. Schaefer +16
We observe the brightest member of the Praesepe cluster, Epsilon Cancri, to precisely measure the characteristics of the stars in this binary system, en route to a new measurement…
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…
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…
