Abstract:
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 our
diameters with Gaia or Hipparcos parallaxes to calculate each star's
physical radius. We gathered information from the literature to
determine bolometric flux and luminosity, and combined that with our
diameters to produce an effective temperature. Our sample consists of
mostly giant stars, and spans a wide range of spectral classes from B
to M.
Description:
The Navy Precision Optical Interferometer (NPOI) is an optical
interferometer located on Anderson Mesa, AZ. The NPOI uses a 12.5cm
diameter region of a 50cm siderostat in both the astrometric and
imaging stations. We can combine light from any of the astrometric and
imaging stations that are appropriate for our science goals, up to six
stations at a time. The current magnitude limit is ∼5.5 in the V band
under normal conditions and ∼6.0 in excellent conditions.
We observed the 44 targets from 1997 to 2021, a data set that totals
over 85000 calibrated data points.
