We apply the infrared surface brightness method of Fouque and Gieren to a sample of 32 Galactic Cepheids with excellent photometric and radial velocity data. The distance solutions are fully consistent with recent direct interferometric Cepheid distance measurements, and with Hipparcos parallaxes of nearby Cepheid variables, but are more accurate than these determinations. Fitting the slopes observed...
We have applied the near-infrared surface-brightness method to 111 Cepheids in the Milky Way and in the Large and the Small Magellanic Clouds determining distances and luminosities for the individual stars. We find that the K-band Period-Luminosity (PL-)relations for Milky Way and Large Magellanic Cloud Cepheids are almost identical, whereas the zero point of the Wesenheit relation depends significantly...
