Abstract:
Using data from Gaia DR3, we construct a sample of 14791
gravitationally bound wide pairs in which one of the components is an
unresolved binary with an astrometric orbital or acceleration
solution. These systems are hierarchical triples, with inner binary
separations of order 1au, and outer separations of 100-100000au.
Leveraging the fact that the inner binary and outer tertiary should
have nearly identical parallaxes, we use the sample to calibrate the
parallax uncertainties for orbital and acceleration binary solutions.
We find that the parallax uncertainties of orbital solutions are
typically underestimated by a factor of 1.3 at G>14, and by a factor
of 1.7 at G=8-14. The true parallax uncertainties are nevertheless
a factor of ∼10 smaller than those of the single-star astrometric
solutions for the same sources. The parallax uncertainties of
acceleration solutions are underestimated by larger factors of 2-3
but still represent a significant improvement compared to the
sources' single-star solutions. We provide tabulated uncertainty
inflation factors for astrometric binary solutions and make the
catalog of hierarchical triples publicly available.
Description:
We present a catalog of 14791 gravitationally bound wide pairs where
one of the components is an unresolved binary with an astrometric
orbital or acceleration solution in Gaia DR3. The catalog is separated
into two tables corresponding to orbital solutions and acceleration
solutions, respectively.
