The methods of calibrating the luminosities of galactic Cepheids and determining Cepheid reddenings are considered in some detail. Together with work on NGC4258 this suggests that the calibration presented is valid to about 0.1 mag (s.e.) at least for Cepheids with near solar abundances. Metallicity effects are considered, partly through the use of non-Cepheid moduli of the LMC. To reduce the uncertainty substantially below ∼ 0.1 mag will require extensive work on metallicity effects. Non… 

The effect of metallicity on the Cepheid period-luminosity relation

We present preliminary results of an observational campaign devoted to establishing the influence of chemical composition on the Cepheid Period-Luminosity relation. The data are in good agreement

The metallicity dependence of the Cepheid PL-relation

A sample of 37 Galactic, 10 LMC and 6 SMC cepheids is compiled for which individual metallicity estimates exist and BVIK  photometry in almost all cases. The Galactic cepheids all have an individual

ON THE APPLICATION OF WESENHEIT FUNCTION IN DERIVING DISTANCE TO GALACTIC CEPHEIDS

In this paper, we explore the possibility of using the Wesenheit function to derive individual distances to Galactic Cepheids, as the dispersion of the reddening-free Wesenheit function is smaller

Period–luminosity relations for Galactic Cepheid variables with independent distance measurements

In this paper, we derive the period-luminosity (PL) relation for Galactic Cepheids with recent independent distance measurements from open cluster, Barnes-Evans surface brightness, interferometry and

UPDATED 24 μm PERIOD–LUMINOSITY RELATION DERIVED FROM GALACTIC CEPHEIDS

In this work, we updated the catalog of Galactic Cepheids with 24 μm photometry by cross-matching the positions of known Galactic Cepheids to the recently released MIPSGAL point source catalog. We

The Distances to Open Clusters from Main-Sequence Fitting. IV. Galactic Cepheids, the LMC, and the Local Distance Scale

We derive the basic properties of seven Galactic open clusters containing Cepheids and construct their period-luminosity (P-L) relations. For our cluster main-sequence fitting we extend previous

Carbon-rich Mira variables: kinematics and absolute magnitudes

The kinematics of Galactic C-Miras are discussed on the basis of the bolometric magnitudes and radial velocities of Papers I and II of this series. Differential Galactic rotation is used to derive a

The Araucaria Project: An Improved Distance to the Sculptor Spiral Galaxy NGC 300 from Its Cepheid Variables

In a previous paper, we reported on the discovery of more than a hundred new Cepheid variables in the Sculptor Group spiral galaxy NGC 300 from wide-field images taken in the B and V photometric

The Araucaria Project: Near-Infrared Photometry of Cepheid Variables in the Sculptor Galaxy NGC 55

We have obtained deep images in the near-infrared J and K filters of four fields in the Sculptor group spiral galaxy NGC 55 with the ESO VLT and ISAAC camera. For 40 long-period Cepheid variables in

The linearity of the Wesenheit function for the Large Magellanic Cloud Cepheids

There is strong evidence that the period-luminosity (PL) relation for the Large Magellanic Cloud (LMC) Cepheids shows a break at a period around 10 d. Because the LMC PL relation is extensively used
