Abstract:
The Cepheid period-luminosity (PL) relation is the key tool for
measuring astronomical distances and for establishing the
extragalactic distance scale. In particular, the local value of the
Hubble constant (H0) strongly depends on Cepheid distance
measurements. The recent Gaia Data Releases and other parallax
measurements from the Hubble Space Telescope (HST) already enabled us
to improve the accuracy of the slope (α) and intercept (β)
of the PL relation. However, the dependence of this law on metallicity
is still largely debated. In this paper, we combine three samples of
Cepheids in the Milky Way (MW), the Large Magellanic Cloud (LMC), and
the Small Magellanic Cloud (SMC) in order to derive the metallicity
term (hereafter γ) of the PL relation. The recent publication of
extremely precise LMC and SMC distances based on late-type detached
eclipsing binary systems provides a solid anchor for the Magellanic
Clouds. In the MW, we adopt Cepheid parallaxes from the early third
Gaia Data Release. We derive the metallicity effect in V, I, J, H,
KS, WVI, and WJK. In the KS band we report a metallicity
effect of -0.221±0.051mag/dex, the negative sign meaning that more
metal-rich Cepheids are intrinsically brighter than their more
metal-poor counterparts of the same pulsation period.
