The Leavitt law of Milky Way Cepheids from Gaia DR2 static companion parallaxes

, 2020
International audienceClassical Cepheids (CCs) are at the heart of the empirical extragalactic distance ladder. Milky Way CCs are the only stars of this class accessible to trigonometric parallax measurements.

Using Galactic Cepheids to verify Gaia parallaxes

, 2011
Context. The Gaia satellite will measure highly accurate absolute parallaxes of hundreds of millions of stars by comparing the parallactic displacements in the two fields of view of the optical instrument.

Astrophysical validation of Gaia parallaxes

, 2010
The Gaia satellite, to be launched in August 2012, will measure highly accurate absolute parallaxes of hundreds of millions of stars. This is done by comparing parallactic displacement of stars in different parts of the sky.

How to use Gaia parallaxes for stars with poor astrometric fits

The Open Journal of Astrophysics
Gaia parallax measurements for stars with poor astrometric fits -- as evidenced by high renormalized unit weight error (RUWE) -- are often assumed to be unreliable, but the extent and nature of their biases remain poorly quantified.

Gaia Data Release 2: using Gaia parallaxes

Context. The second Gaia.data release (Gaia DR2 ) provides precise five-parameter astrometric data (positions, proper motions and parallaxes) for an unprecendented amount of sources (more than 1.3 billion, mostly stars).

On the discrepancy between asteroseismic and Gaia DR1 TGAS parallaxes

, 2017
Recently, a deviation of the Gaia Tycho–Gaia Astrometric Solution (TGAS) parallaxes from the asteroseismic ones for giants was found. We show that for parallaxes ϖ < 1.5 mas it can be explained by a selection effect in favour of bright and ...

Testing parallaxes with local Cepheids and RR Lyrae stars

, 2017
Context: 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 ...
