Exoplanet Characterization and the Search for Life (2009)

Kasting, J., Traub, W., Roberge, A., Leger, A., Schwartz, A., Wooten, A., ...

Over 300 extrasolar planets (exoplanets) have been detected orbiting nearby stars. We now hope to conduct a census of all planets around nearby stars and to characterize their atmospheres and...

Imaging and Modeling Rapidly Rotating Stars: Alpha Cephei and Alpha Ophiuchi (2009)

Zhao, M., Monnier, J. D., Pedretti, E., Thureau, N., Merand, A., Brummelaar, T. Ten, ...

We present sub-milliarcseond resolution imaging and modeling of two nearby rapid rotators Alpha Cephei and Alpha Ophiuchi, obtained with the CHARA array - the largest optical/IR interferometer in the...

Dust in the inner regions of debris disks around A stars (2008)

Akeson, R. L., Ciardi, D. R., Millan-Gabet, R., Merand, A., Di Folco, E., Monnier, J. D., ...

We present infrared interferometric observations of the inner regions of two A-star debris disks, beta Leo and zeta Lep, using the FLUOR instrument at the CHARA interferometer on both short (30 m)...

A Tale of Two Herbig Ae stars -MWC275 and AB Aurigae: Comprehensive Models for SED and Interferometry (2008)

Tannirkulam, A., Monnier, J. D., Harries, T. J., Millan-Gabet, R., Zhu, Z., Pedretti, E., ...

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 interferometry (from...

First Resolved Images of the Eclipsing and Interacting Binary Beta Lyrae (2008)

Zhao, M., Gies, D., Monnier, J. D., Thureau, N., Pedretti, E., Baron, F., ...

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 the mass donor and...

Imaging the Surface of Altair (2007)

Monnier, John D., Zhao, M., Pedretti, E., Thureau, N., Ireland, M., Muirhead, P., ...

Spatially resolving the surfaces of nearby stars promises to advance our knowledge of stellar physics. Using optical long-baseline interferometry, we present here a near-infrared image of the rapidly...

The Angular Diameter of λ Boötis (2007)

Ciardi, David R., Van Belle, Gerard T., Boden, Andrew F., Brummelaar, T. Ten, McAlister, H. A., ...

Using the CHARA Array and the Palomar Testbed Interferometer, the chemically peculiar star λ Boötis has been spatially resolved. We have measured the limb darkened angular diameter to be θ_(LD) =...

Extended envelopes around Galactic Cepheids III. Y Oph and alpha Per from near-infrared interferometry with CHARA/FLUOR (2007)

Mérand, A., Audenberg, J., Kervella, P., Foresto, V. Coudé Du, Brummelaar, T. Ten, McAlister, H.

Unbiased angular diameter measurements are required for accurate distances to Cepheids using the interferometric Baade Wesselink method (IBWM). The precision of this technique is currently limited by...

The Angular Diameter of $\lambda$ Bo\"{o}tis} (2006)

Ciardi, David R., Van Belle, Gerard T., Boden, Andrew F., Brummelaar, T. Ten, McAlister, H. A., Bagnuolo, W. G., ...

Using the CHARA Array and the Palomar Testbed Interferometer, the chemically peculiar star $\lambda$ Bo\"{o}tis has been spatially resolved. We have measured the limb darkened angular diameter to be...

First Results from the CHARA Array. III. Oblateness, Rotational Velocity and Gravity Darkening of Alderamin (2005)

Van Belle, G. T., Ciardi, D. R., Brummelaar, T. Ten, McAlister, H. A., Ridgway, S. T., Berger, D. H., ...

We present observations of the A7IV-V star Alderamin ($\alpha$ Cep, HR 8162, HD 203280) from the Georgia State University CHARA Array. These infrared interferometric angular size measurements...
