Abstract:
High-precision stellar masses and radii measured directly from
binaries can effectively calibrate stellar models. However, such a
database containing full spectral types and a large range of
metallicity is still not fully established. A continuous effort of
data collection and analysis is requested to complete the database. In
this work, we provide a catalog containing 184 binaries with
independent atmospheric parameters and accurate masses and radii as
the benchmark for stellar mass and radius. The catalog contains 56 new
detached binaries from the LAMOST medium-resolution spectroscopic
survey and 128 detached eclipsing binaries compiled from previous
studies. We obtain the orbital solutions of the new detached binaries
with uncertainties of masses and radii smaller than 5%. These new
samples densify the distribution of metallicity of the high-precision
stellar mass library and add nine hot stars with Teff>8000K.
Comparisons show that these samples agree well with the PARSEC
isochrones in Teff-logg-mass-radius-luminosity space. We compare mass
and radius estimates from isochrone and spectral energy distribution
fitting, respectively, with those from the binary orbital solution. We
find that the precision of the stellar-model-dependent mass estimates
is >10% and the precision of the radius estimates based on atmospheric
parameters is >15%. These give a general view of the uncertainty of
the usual approaches to estimate stellar mass and radius.
Description:
Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) is
a 4m class reflective Schmidt telescope with a 5deg field of view. A
total of 4000 fibers are installed at its 1.75m diameter focal plane.
In 2018 October, LAMOST started the 5yr medium-resolution
spectroscopic (MRS) survey (R∼7500 with limiting magnitude of G<15
mag), which includes a time-domain spectroscopic survey subproject.
