THE CHARA ARRAY ANGULAR DIAMETER OF HR 8799 FAVORS PLANETARY MASSES FOR ITS IMAGED COMPANIONS
HR 8799 is an hF0 mA5 γ Doradus-, λ Bootis-, Vega-type star best known for hosting four directly imaged candidate planetary companions. Using the CHARA Array interferometer, we measure HR 8799'sExpand
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 ofExpand
CHARA ARRAY MEASUREMENTS OF THE ANGULAR DIAMETERS OF EXOPLANET HOST STARS
Wehavemeasuredtheangulardiametersforasampleof 24exoplanethoststarsusingGeorgiaStateUniversity’s CHARA Array interferometer. We use these improved angular diameters together with Hipparcos parallaxExpand
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 ArrayExpand
Direct measurement of the radius and density of the transiting exoplanet HD 189733B with the Chara array
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 +/- 0.024Expand
Confirming Fundamental Properties of the Exoplanet Host Star epsilon Eridani Using the Navy Optical Interferometer
We measured the angular diameter of the exoplanet host star Eridani using the Navy Optical Interferometer. We determined its physical radius, effective temperature, and mass by combining ourExpand
The expanding fireball of Nova Delphini 2013
TLDR
Near-infrared interferometric measurements of the angular size of Nova Delphini 2013 are reported, suggesting a prolate or bipolar structure that develops as early as the second day of the explosion, and a geometric distance to the nova of 4.54 ± 0.59 kiloparsecs from the Sun. Expand
The Search for Stellar Companions to Exoplanet Host Stars Using the CHARA Array
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 itExpand
THE VISUAL ORBIT OF THE 1.1 DAY SPECTROSCOPIC BINARY σ2CORONAE BOREALIS FROM INTERFEROMETRY AT THE CHARA ARRAY
We present an updated spectroscopic orbit and a new visual orbit for the double-lined spectroscopic binary σ2 Coronae Borealis (CrB) based on radial velocity measurements at the Oak Ridge ObservatoryExpand
The Ages of A-Stars I: Interferometric Observations and Age Estimates for Stars in the Ursa Major Moving Group
We have observed and spatially resolved a set of seven A-type stars in the nearby Ursa Major moving group with the Classic, CLIMB, and PAVO beam combiners on the CHARA Array. At least four of theseExpand
