Abstract:
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR
Lyrae stars in common between Gaia and the Hipparcos and Tycho-2
catalogues are published in Gaia Data Release 1 (DR1) as part of the
Tycho-Gaia Astrometric Solution (TGAS). In order to test these first
parallax measurements of the primary standard candles of the
cosmological distance ladder, that involve astrometry collected by
Gaia during the initial 14 months of science operation, we compared
them with literature estimates and derived new period-luminosity (PL),
period-Wesenheit (PW) relations for classical and Type II Cepheids and
infrared PL, PL-metallicity (PLZ) and optical luminosity-metallicity
(MV-[Fe/H]) relations for the RR Lyrae stars, with zero points based
on TGAS. The new relations were computed using multi-band
(V, I, J, Ks, W1) photometry and spectroscopic metal abundances
available in the literature, and applying three alternative
approaches: (i) by linear least squares fitting the absolute
magnitudes inferred from direct transformation of the TGAS parallaxes,
(ii) by adopting astrometric-based luminosities, and (iii) using a
Bayesian fitting approach. TGAS parallaxes bring a significant added
value to the previous Hipparcos estimates. The relations presented in
this paper represent first Gaia-calibrated relations and form a
"work-in-progress" milestone report in the wait for Gaia-only
parallaxes of which a first solution will become available with Gaia's
Data Release 2 (DR2) in 2018.
Description:
