The Leavitt law of Milky Way Cepheids from Gaia DR2 static companion parallaxes
Louise Breuval, Pierre Kervella, Frédéric Arenou +13
Classical 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 measur…
A thin shell of ionized gas explaining the IR excess of classical Cepheids
V. Hocdé, N. Nardetto, E. Lagadec +12
Despite observational evidences, InfraRed (IR) excess of classical Cepheids are seldom studied and poorly understood, but probably induces systematics on the Period-Luminosity (PL)…
Consistent radial velocities of classical Cepheids from the cross-correlation technique
Simon Borgniet, Pierre Kervella, Nicolas Nardetto +11
Accurate radial velocities () of Cepheids are mandatory within the context of distance measurements via the Baade-Wesselink technique. The most common de…
Testing systematics of Gaia DR2 parallaxes with empirical surface brightness -- color relations applied to eclipsing binaries
Dariusz Graczyk, Grzegorz Pietrzynski, Wolfgang Gieren +18
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 st…
