We present the first results from an ongoing survey for multiplicity among the bright stars using the Navy Precision Optical Interferometer (NPOI). We first present a summary of NPOI observations of known multiple systems, including the first detection of the companion of $\beta$ Scuti with precise relative astrometry, to illustrate the instrument's detection sensitivity for binaries at magnitude differences $\Delta$$m$ $\lessapprox$ 3 over the range of angular separation 3 - 860… Expand
The disk physical conditions of 48 Persei constrained by contemporaneous H{\alpha} spectroscopy and interferometry
We utilize a multi-step modelling process to produce synthetic interferometric and spectroscopic observables, which are then compared to their observed counterparts. Our extensive set ofExpand
Precise calibration of the dependence of surface brightness–colour relations on colour and class for late-type stars
Surface brightness-colour relations (SBCRs) are used to derive the stellar angular diameters from photometric observations. They have various astrophysical applications, such as the distanceExpand
Fundamental Parameters of 87 Stars from the Navy Precision Optical Interferometer
We present the fundamental properties of 87 stars based on angular diameter measurements from the Navy Precision Optical Interferometer, 36 of which have not been measured previously usingExpand
The Navy Precision Optical Interferometer: two years of development towards large-aperture observations
We have been pursuing a comprehensive program of improving high-resolution imaging at the Navy Precision Optical Interferometer (NPOI) hosted at Lowell Observatory’s Anderson Mesa site, for theExpand
Many interesting things are afoot at the Navy Precision Optical Interferometer
TLDR
Baseline-wavelength bootstrapping will be implemented on the facility back-end with a near-infrared beam combiner under development, marking substantial progress in taking the NPOI towards realizing its full intrinsic potential. Expand
