Abstract:
Using a sample of 81 Galactic, detached eclipsing binary stars we
investigated the global zero-point shift of their parallaxes with the
Gaia Data Release 2 (DR2) parallaxes. The stars in the sample lay in a
distance range of 0.04-2kpc from the Sun. The photometric parallaxes
ωPhot of the eclipsing binaries were determined by applying a
number of empirical surface brightness-color (SBC) relations
calibrated on optical-infrared colors. For each SBC relation we
calculated the individual differences
dϖi=(ϖGaia-ϖPhot)i and then we calculated
unweighted and weighted means. As the sample covers the whole sky we
interpret the weighted means as the global shifts of the Gaia DR2
parallaxes with respect to our eclipsing binary sample. Depending on
the choice of the SBC relation the shifts vary from -0.094 to
-0.025mas. The weighted mean of the zero-point shift from all colors
and calibrations used is dω=-0.054±0.024mas. However, the SBC
relations based on (B-K) and (V-K) colors, which are the least
reddening dependent and have the lowest intrinsic dispersions, give a
zero-point shift of dω=-0.031±0.011mas in full agreement with
results obtained by Lindegren+ (2018A&A...616A...2L 2018A&A...616A...2L) and
Arenou+ (2018A&A...616A..17A 2018A&A...616A..17A). Our result confirms the global shift of
Gaia DR2 parallaxes of dω=-0.029mas reported by the Gaia team,
but we do not confirm the larger zero-point shift reported by a number
of follow-up papers.
Description:
We extended the sample of 35 eclipsing binaries compiled by
Graczyk+ (2017ApJ...837....7G 2017ApJ...837....7G) by searching for detached systems in
the literature suitable for a precise distance determination.
Our sample contains 81 systems (51 on the northern hemisphere and 30
on the southern one). Their basic parameters are presented in Table 1.
We used Tycho-2 BT and VT photometry (Hog+ 2000, I/259) downloaded
from Vizier. The Tycho photometry was subsequently transformed onto
the Johnson system using the method outlined by
Bessell (2000PASP..112..961B 2000PASP..112..961B). Whenever possible we used Johnson B, V
photometry from the compilation of Mermilliod (1997, II/168) and also
absolute optical photometry from literature sources.
