Diameters and Temperatures VII: High-angular resolution measurements of Solar-type stars with the CHARA Array
Tabetha S. Boyajian, Ashley A. Elliott, Emelly D. Tiburcio +8
We present interferometric measurements of angular diameters for 27 nearby solar-type stars obtained with the Precision Astronomical Visible Observations (PAVO) beam combiner at th…
The Debris Disk Host Piscis Austrinus is a Rapidly Rotating Star Seen Nearly Pole-On
Colin Kane, Russel White, Jeremy Jones +6
Previous studies of Piscis Austrinus (PsA) have speculated that the narrow and saddle-like shapes of some of its weak metallic lines are a consequence of it being a rapidly rot…
Astro2020 Science White Paper: High Angular Resolution Astrophysics - Fundamental Stellar Parameters
Gerard van Belle, Ellyn Baines, Tabetha Boyajian +8
Direct determination of fundamental stellar parameters has many profound and wide-ranging impacts throughout astrophysics. These determinations are rooted in high angular resolutio…
A Low-Mass Black Hole in the Nearby Seyfert Galaxy UGC 06728
Misty C. Bentz, Merida Batiste, James Seals +14
We present the results of a recent reverberation mapping campaign for UGC 06728, a nearby low-luminosity Seyfert 1 in a late-type galaxy. Nightly monitoring in the spring of 2015 a…
The Age of the Directly-Imaged Planet Host Star Andromedae Determined From Interferometric Observations
Jeremy Jones, R. J. White, S. Quinn +4
Andromedae, an early type star that hosts a directly imaged low mass companion, is expected to be oblate due to its rapid rotational velocity ( = 162 $\mathrm{km…
Spectroscopy, MOST Photometry, and Interferometry of MWC 314: Is it an LBV or an interacting binary?
Noel D. Richardson, Anthony F. J. Moffat, Raphaël Maltais-Tariant +34
MWC 314 is a bright candidate luminous blue variable that resides in a fairly close binary system, with an orbital period of 60.7530.003 d. We observed MWC 314 with a combinat…
The Ages of A-Stars I: Interferometric Observations and Age Estimates for Stars in the Ursa Major Moving Group
Jeremy Jones, R. J. White, T. Boyajian +12
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 le…
Stellar Diameters and Temperatures VI. High angular resolution measurements of the transiting exoplanet host stars HD 189733 and HD 209458 and implications for models of cool dwarfs
Tabetha Boyajian, Kaspar von Braun, Gregory A. Feiden +24
We present direct radii measurements of the well-known transiting exoplanet host stars HD 189733 and HD 209458 using the CHARA Array interferometer. We find the limb-darkened angul…
The Mass of the Central Black Hole in the Nearby Seyfert Galaxy NGC5273
Misty C. Bentz, Daniel Horenstein, Craig Bazhaw +9
We present the results of a reverberation-mapping program targeting NGC5273, a nearby early-type galaxy with a broad-lined active galactic nucleus. Over the course of the monitorin…
Stellar Diameters and Temperatures V. Eleven Newly Characterized Exoplanet Host Stars
Kaspar von Braun, Tabetha S. Boyajian, Gerard T. van Belle +17
We use near-infrared interferometric data coupled with trigonometric parallax values and spectral energy distribution fitting to directly determine stellar radii, effective tempera…
Stellar Diameters and Temperatures III. Main Sequence A, F, G, & K Stars: Additional high-precision measurements and empirical relations
Tabetha S. Boyajian, Kaspar von Braun, Gerard van Belle +13
Based on CHARA Array measurements, we present the angular diameters of 23 nearby, main- sequence stars, ranging from spectral type A7 to K0, five of which are exoplanet host stars.…
The CHARA Array Angular Diameter of HR 8799 Favors Planetary Masses for Its Imaged Companions
Ellyn K. Baines, Russel J. White, Daniel Huber +13
HR 8799 is an hF0 mA5 gamma Doradus, lambda Bootis, Vega-type star best known for hosting four directly imaged candidate planetary companions. Using the CHARA Array interferometer,…
Stellar Diameters and Temperatures II. Main Sequence K & M Stars
Tabetha S. Boyajian, Kaspar von Braun, Gerard van Belle +21
We present interferometric diameter measurements of 21 K- and M- dwarfs made with the CHARA Array. This sample is enhanced by literature radii measurements to form a data set of 33…
