Angular Diameters of the Hyades Giants Measured with the CHARA Array
Tabetha S. Boyajian, Harold A. McAlister, Justin R. Cantrell +8
We present angular diameters of the Hyades giants, gamma, delta^1, epsilon, and theta^1 Tau from interferometric measurements with the CHARA Array. Our errors in the limb-darkened…
A Tale of Two Herbig Ae stars -MWC275 and AB Aurigae: Comprehensive Models for SED and Interferometry
A. Tannirkulam, J. D. Monnier, T. J. Harries +12
We present comprehensive models for the Herbig Ae stars MWC275 and AB Aur that aim to explain their spectral energy distribution (from UV to millimeter) and long baseline interfero…
First Resolved Images of the Eclipsing and Interacting Binary Beta Lyrae
M. Zhao, D. Gies, J. D. Monnier +12
We present the first resolved images of the eclipsing binary Beta Lyrae, obtained with the CHARA Array interferometer and the MIRC combiner in the H band. The images clearly show t…
The radii of the nearby K5V and K7V stars 61 Cyg A & B - CHARA/FLUOR interferometry and CESAM2k modeling
Pierre Kervella, Antoine Mérand, Bernard Pichon +11
Context: The main sequence binary star 61 Cyg (K5V+K7V) is our nearest stellar neighbour in the northern hemisphere. This proximity makes it a particularly well suited system for v…
Angular Diameters of the G Subdwarf Cassiopeiae A and the K Dwarfs Draconis and HR 511 from Interferometric Measurements with the CHARA Array
Tabetha S. Boyajian, Harold A. McAlister, Ellyn K. Baines +13
Using the longest baselines of the CHARA Array, we have measured the angular diameter of the G5 V subdwarf Cas A, the first such determination for a halo population star. We co…
The Long Period, Massive Binaries HD 37366 and HD 54662: Potential Targets for Long Baseline Optical Interferometry
T. S. Boyajian, D. R. Gies, J. P. Dunn +8
We present the results from an optical spectroscopic analysis of the massive stars HD 37366 and HD 54662. We find that HD 37366 is a double-lined spectroscopic binary with a period…
