Eleven Exoplanet Host Star Angular Diameters from the CHARA Array (2009)
Baines, Ellyn K., McAlister, Harold A., Brummelaar, Theo A. Ten, Sturmann, J., Sturmann, L., Turner, Nils H., ...
We directly measured the angular diameters for 11 exoplanet host stars using Georgia State University's CHARA Array interferometer and calculated their linear radii and effective temperatures. The...
Angular Diameters of the Hyades Giants Measured with the CHARA Array (2008)
Boyajian, Tabetha S., McAlister, Harold A., Cantrell, Justin R., Gies, Douglas R., Brummelaar, Theo A. Ten, Farrington, Chris, ...
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 angular diameters...

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 very high accuracy...
Boyajian, Tabetha S., McAlister, Harold A., Baines, Ellyn K., Gies, Douglas R., Henry, Todd, Jao, Wei-Chun, ...
Using the longest baselines of the CHARA Array, we have measured the angular diameter of the G5 V subdwarf $\mu$ Cas A, the first such determination for a halo population star. We compare this result...
The Search for Stellar Companions to Exoplanet Host Stars Using the CHARA Array (2008)
Baines, Ellyn K., McAlister, Harold A., Brummelaar, Theo A. Ten, Turner, Nils H., Sturmann, Judit, Sturmann, Laszlo, ...
Most exoplanets have been discovered via radial velocity studies, which are inherently insensitive to orbital inclination. Interferometric observations will show evidence of a stellar companion if it...
CHARA Array Measurements of the Angular Diameters of Exoplanet Host Stars (2008)
Baines, Ellyn K., McAlister, Harold A., Brummelaar, Theo A. Ten, Turner, Nils H., Sturmann, Judit, Sturmann, Laszlo, ...
We have measured the angular diameters for a sample of 24 exoplanet host stars using Georgia State University's CHARA Array interferometer. We use these improved angular diameters together with...

We have measured the angular diameter of the transiting extrasolar planet host star HD 189733 using the CHARA optical/IR interferometric array. Combining our new angular diameter of 0.377 +/- 0.024...

Cepheids play a key role in astronomy as standard candles for measuring intergalactic distances. Their distance is usually inferred from the Period-Luminosity relationship, calibrated using the...
Using Small Aperture Interferometry to Detect Planets in Nearby Binary Star Systems, (2002)
Currie,Douglas G., McAlister,Harold A., Schneeberger,Timothy J., Worden,Simon P.
If suitably accurate binary star orbits can be observed, the effects of planets in the binary star system may be detectable in the reflex motion of the component binary stars. We show that...
Speckle interferometric methods provide a means for reconstructing diffraction limited images from atmospherically blurred image data obtained in snapshots with exposure times shorter than the...
