Query: ARIADNE: Measuring accurate and precise stellar parameters through SED
  fitting   Accurately measuring stellar parameters is a key goal to increase our
understanding of the observable universe. However, current methods are limited
by many factors, in particular, the biases and physical assumptions that are
the basis for the underlying evolutionary or atmospheric models, those that
these methods rely upon. Here we introduce our code spectrAl eneRgy
dIstribution bAyesian moDel averagiNg fittEr (ARIADNE), which tackles this
problem by using Bayesian Model Averaging to incorporate the information from
all stellar models to arrive at accurate and precise values. This code uses
spectral energy distribution fitting methods, combined with precise Gaia
distances, to measure the temperature, log g, [Fe/H], A$_{\text V}$, and radius
of a star. When compared with interferometrically measured radii ARIADNE
produces values in excellent agreement across a wide range of stellar
parameters, with a mean fractional difference of only 0.001 $\pm$ 0.070. We
currently incorporate six different models, and in some cases we find
significant offsets between them, reaching differences of up to 550 K and 0.6
R$_\odot$ in temperature and radius, respectively. For example, such offsets in
stellar radius would give rise to a difference in planetary radius of 60%,
negating homogeneity when combining results from different models. We also find
a trend for stars smaller than 0.4-0.5 R$_\odot$, which shows more work needs
to be done to better model these stars, even though the overall extent is
within the uncertainties of the interferometric measurements. We advocate for
the use of ARIADNE to provide improved bulk parameters of nearby A to M dwarfs
for future studies.
