Abstract:
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 using interferometry.
Our sample consists of 5 dwarfs, 3 subgiants, 69 giants, 3 bright
giants, and 7 supergiants, and span a wide range of spectral classes
from B to M. We combined our angular diameters with photometric and
distance information from the literature to determine each star's
physical radius, effective temperature, bolometric flux, luminosity,
mass, and age.
Description:
The Navy Precision Optical Interferometer (NPOI) is an optical
interferometer located on Anderson Mesa, AZ (see Armstrong et al.
1998ApJ...496..550A 1998ApJ...496..550A for the instrument description and Hummel et al.
2003AJ....125.2630H 2003AJ....125.2630H and Benson et al. 2003SPIE.4838..358B 2003SPIE.4838..358B for details
about the beam combiner). The NPOI consists of two nested arrays: the
four fixed stations of the astrometric array (AC, AE, AW, and AN, which
stand for astrometric center, east, west, and north, respectively)
that are clustered at the center of the array, and the stations of the
imaging array.
We observed 87 stars from 2004 to 2016, a data set that totals over
100000 calibrated data points. We used the "Classic" beam combiner
that takes data over 16 spectral channels spanning 550-850 nm
(Hummel et al. 2003AJ....125.2630H 2003AJ....125.2630H; Hutter et al. 2016ApJS..227....4H 2016ApJS..227....4H).
Each observation consisted of a 30 s coherent (on the fringe) scan where
the fringe contrast was measured every 2 ms. Every coherent scan was
paired with an incoherent (off the fringe) scan that was used to estimate
the additive bias affecting fringe measurements (Hummel et al.
2003AJ....125.2630H 2003AJ....125.2630H).

The other parameters are derived as described in Section 3.2.
Note (2): Flag as follows:
* = The large error on the parallax measurement made the radius determination
unuseful, considering the error would be more than 50%.
Note (3): Flag as follows:
* = Because the errors on the parallax measurements are unusually high
(≥20%), the errors on the subsequent luminosity calculations render them
unhelpful for these stars.
