Directly Determined Linear Radii and Effective Temperatures of Exoplanet Host Stars (2009)
Van Belle, Gerard T., Von Braun, Kaspar
We present interferometric angular sizes for 12 stars with known planetary companions, for comparison with 28 additional main-sequence stars not known to host planets. For all objects we estimate...

The Palomar Testbed Interferometer Calibrator Catalog (2008)
Van Belle, Gerard T., Van Belle, G., Creech-Eakman, M. J., Coyne, J., Boden, A. F., Akeson, R. L., ...
The Palomar Testbed Interferometer (PTI) archive of observations between 1998 and 2005 is examined for objects appropriate for calibration of optical long-baseline interferometer observations—stars...
Spitzer 24 μm time series observations of the eclipsing M dwarf binary GU Boötis (2008)
Von Braun, Kaspar, Van Belle, Gerard T., Ciardi, David R., Lopez-Morales, Mercedes, Hoard, D. W., Wachter, Stefanie
We present a set of Spitzer 24 μm MIPS time series observations of the M dwarf eclipsing binary star GU Boötis. Our data cover three secondary eclipses of the system: two consecutive events and an...

Von Braun, Kaspar, Van Belle, Gerard T., Ciardi, David R., Lopez-Morales, Mercedes, Hoard, D. W., Wachter, Stefanie
We present a set of {\it Spitzer} 24$\mu$m MIPS time series observations of the M-dwarf eclipsing binary star GU Bo\"otis. Our data cover three secondary eclipses of the system: two consecutive...
The Spitzer 24-micron Photometric Light Curve of the Eclipsing M-dwarf Binary GU Bootis (2007)
Von Braun, Kaspar, Van Belle, Gerard T., Ciardi, David, Lopez-Morales, Mercedes, Hoard, D. W., Wachter, Stefanie
We present a carefully controlled set of Spitzer 24 \micron MIPS time series observations of the low mass eclipsing binary star GU Bo\"otis (GU Boo). Our data cover three secondary eclipses of the...
Baines, Ellyn K., Van Belle, Gerard T., Ten Brummelaar, Theo A., McAlister, Harold A., Swain, Mark, Turner, Nils H., ...
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...
