Stellar Diameters and Temperatures. II. Main-sequence K- and M-stars
We present interferometric angular diameter measurements of 21 low-mass, K- and M-dwarfs made with the CHARA Array. This sample is enhanced by adding a collection of radius measurements published in
Imaging the Surface of Altair
TLDR
Using optical long-baseline interferometry, a near-infrared image of the rapidly rotating hot star Altair is constructed with a resolution of <1 milliarcsecond that clearly reveals the strong effect of gravity darkening on the highly distorted stellar photosphere.
First Results from the CHARA Array. VII. Long-Baseline Interferometric Measurements of Vega Consistent with a Pole-On, Rapidly Rotating Star
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
Circumstellar material in the Vega inner system revealed by CHARA/FLUOR
Context. 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
First Results from the CHARA Array. II. A Description of the Instrument
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
Extended envelopes around Galactic Cepheids. II. Polaris and delta Cephei from near-infrared interfe
We present the results of long-baseline interferometric observations of the classical Cepheids Polaris and δ  Cep in the near infrared K'  band (1.9-2.3  μ m), using the FLUOR instrument of the CHARA
First Results from the CHARA Array. I. An Interferometric and Spectroscopic Study of the Fast Rotator α Leonis (Regulus)
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
The projection factor of δ Cephei A calibration of the Baade-Wesselink method using the CHARA Array
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
CHARA Array K'-Band Measurements of the Angular Dimensions of Be Star Disks
We present the firstK 0 -band,long-baseline interferometric observations of the northern Be starsCas,� Per,� Tau, andDra. The measurements were made with multiple telescope pairs of the CHARA Array
First Results from the CHARA Array. IV. The Interferometric Radii of Low-Mass Stars
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 Vand
