A near-infrared interferometric survey of debris disc stars. II. CHARA/FLUOR observations of six early-type dwarfs (2008)

Absil, O., Di Folco, E., Merand, A., Foresto, V. Coude Du, Defrere, D., ...

High-precision interferometric observations of six early-type main sequence stars known to harbour cold debris discs have been obtained in the near-infrared K band with the FLUOR instrument at the...

Strong Near-Infrared Emission Interior to the Dust-Sublimation Radius of Young Stellar Objects MWC275 and AB Aur (2008)

Tannirkulam, A., Monnier, J. D., Millan-Gabet, R., Harries, T. J., Pedretti, E., Brummelaar, T. A. Ten, ...

Using the longest optical-interferometeric baselines currently available, we have detected strong near-infrared (NIR) emission from inside the dust-destruction radius of Herbig Ae stars MWC275 and AB...

A near-infrared interferometric survey of debris disk stars. I. Probing the hot dust content around epsilon Eridani and tau Ceti with CHARA/FLUOR (2007)

Di Folco, E., Absil, O., Mérand, A., Foresto, V. Coudé Du, Thévenin, F., ...

We probed the first 3AU around tau Ceti and epsilon Eridani with the CHARA array (Mt Wilson, USA) in order to gauge the 2micron excess flux emanating from possible hot dust grains in the debris disks...

Direct Measurement of the Radius and Density of the Transiting Exoplanet HD 189733B with the CHARA Array (2007)

Baines, E. K., Van Belle, G. T., Brummelaar, T. A. Ten, McAlister, H. A., Swain, M., Turner, N. H., ...

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

CHARA Array K'-band Measurements of the Angular Dimensions of Be Star Disks (2006)

Gies, D. R., Bagnuolo, W. G., Baines, E. K., Brummelaar, T. A. Ten, Farrington, C. D., ...

We present the first K'-band, long-baseline interferometric observations of the northern Be stars gamma Cas, phi Per, zeta Tau, and kappa Dra. The measurements were made with multiple telescope pairs...

Circumstellar material in the Vega inner system revealed by CHARA/FLUOR (2006)

Absil, O., Di Folco, E., Merand, A., Foresto, V. Coude Du, Aufdenberg, J. P., ...

Only a handful of debris disks have been imaged up to now. Due to the need for high dynamic range and high angular resolution, very little is known about the inner planetary region, where small...

First Results from the CHARA Array VII: Long-Baseline Interferometric Measurements of Vega Consistent with a Pole-On, Rapidly Rotating Star (2006)

Aufdenberg, J. P., Merand, A., Foresto, V. Coude Du, Absil, O., Di Folco, E., Kervella, P., ...

We have obtained high-precision interferometric measurements of Vega with the CHARA Array and FLUOR beam combiner in the K' band at projected baselines between 103m and 273m. The measured visibility...

First Results from the CHARA Array. IV. The Interferometric Radii of Low-Mass Stars (2006)

Berger, D. H., Gies, D. R., McAlister, H. A., Brummelaar, T. A. Ten, Henry, T. J., Sturmann, J., ...

We have measured the angular diameters of six M dwarfs with the CHARA Array, a long-baseline optical interferometer located at Mount Wilson Observatory. Spectral types range from M1.0 V to M3.0 V and...

Brummelaar, T. A. Ten, McAlister, H. A., Ridgway, S. T., Bagnuolo Jr, W. G., Turner, N. H., Sturmann, L., ...

The CHARA Array is a six 1-m telescope optical/IR interferometric array located on Mount Wilson California, designed and built by the Center for High Angular Resolution Astronomy of Georgia State...

First Results from the CHARA Array. I. An Interferometric and Spectroscopic Study of the Fast Rotator alpha Leonis (Regulus) (2005)

McAlister, H. A., Brummelaar, T. A. Ten, Gies, D. R., Huang, W., Bagnuolo, W. G., ...

We report on K-band interferometric observations of the bright, rapidly rotating star Regulus (type B7 V) made with the CHARA Array on Mount Wilson, California. Through a combination of...
