Simultaneous Six-way Observations from the Navy Precision Optical Interferometer
Ellyn K. Baines, Solvay Blomquist, James H. Clark +7
We measured the angular diameters of six stars using the 6-element observing mode of the Navy Precision Optical Interferometer (NPOI) for the first time since the early 2000s. Four…
Thirty-Three New Stellar Angular Diameters from the NPOI, and Nearly 180 NPOI Diameters as an Ensemble
Ellyn K. Baines, James H. Clark, Henrique R. Schmitt +2
We present new angular diameter measurements for 33 stars from the Navy Precision Optical Interferometer, reaching uncertainties on the limb-darkened diameter of 2% or less for 21…
Angular Diameters and Fundamental Parameters of Forty-Four Stars from the Navy Precision Optical Interferometer
Ellyn K. Baines, J. Thomas Armstrong, James H. Clark +9
We measured the angular diameters of 44 stars with the Navy Precision Optical Interferometer, obtaining uncertainties on the limb darkened diameter of 2% or less for all but four s…
A High Angular Resolution Survey of Massive Stars in Cygnus OB2: Adaptive Optics Results from the Gemini Near-InfraRed Imager
S. M. Caballero-Nieves, D. R. Gies, E. K. Baines +8
We present results of a high angular resolution survey of massive OB stars in the Cygnus OB2 association that we conducted with the NIRI camera and ALTAIR adaptive optics system of…
Interferometric Fringe Visibility Null as a Function of Spatial Frequency: a Probe of Stellar Atmospheres
J. T. Armstrong, A. M. Jorgensen, D. Mozurkewich +4
We introduce an observational tool based on visibility nulls in optical spectro-interferometry fringe data to probe the structure of stellar atmospheres. In a preliminary demonstra…
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…
