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 β Scuti with precise relative astrometry, to illustrate the instrument’s detection sensitivity for binaries at magnitude differences Δm ⪅ 3 over the range of angular separation 3–860 milliarcseconds (mas). A limiting Δm700 ∼ 3…

Precise calibration of the dependence of surface brightness–colour relations on colour and class for late-type stars (Corrigendum)
Context. Surface brightness–colour relations (SBCRs) are used to derive the stellar angular diameters from photometric observations. They have various astrophysical applications, such as the distance
Fundamental Parameters of 87 Stars from the Navy Precision Optical Interferometer

Developments in High Spatial Resolution Imaging of Faint, Complex Objects at Lowell Observatory
We have been pursuing a comprehensive program of high-resolution imaging at Lowell Observatory, for the purpose of spatially resolved observations of faint objects at scales down to less than 1
Angular Diameters and Fundamental Parameters of Forty-four Stars from the Navy Precision Optical Interferometer
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 stars. We then used
A Recipe for Finding Stellar Radii, Temperatures, Surface Gravities, Metallicities, and Masses Using Spectral Lines
A recipe based on physical principles employs the observed equivalent widths of 10 spectral lines to model the photosphere of a target star. Coupled with the visual magnitude and an absolute flux
