Binary Studies with the Navy Precision Optical Interferometer

Abstract

Observations of binary stars are the bread-and-butter for optical interferometers. An easy exploit for the unrivaled angular resolution of long baseline interferometers, the measurement of the orbits of double-lined spectroscopic binaries affords the determination of fundamental parameters of stars as well as their distance from Earth. Interferometry thus extends the reach of using spectroscopic binaries to non-eclipsing pairs, as a special but unlikely geometry for seeing eclipses, which also allow the determination of high-precision stellar masses, is no longer required.
