Period–luminosity relations (PLRs) of type II Cepheids (T2Cs) in the Small Magellanic Cloud (SMC) are derived based on OGLE-III, IRSF/SIRIUS and other data, and these are compared with results for the Large Magellanic Cloud (LMC) and Galactic globular clusters. Evidence is found for a change of the PLR slopes from system to system. Treating the longer period T2Cs (W Vir stars) separately gives an SMC–LMC modulus difference of 0.39 ± 0.05 mag without any metallicity corrections being applied…

The period-luminosity and period-radius relations of Type II and anomalous Cepheids in the Large and Small Magellanic Clouds

Method: In an accompanying paper (arXiv: 1705.00886) we determined luminosity and effective temperature for the 335 T2Cs and ACs in the LMC and SMC discovered in the OGLE-III survey, by constructing

Baade-Wesselink distances to Galactic and Magellanic Cloud Cepheids and the effect of metallicity

Context. The metallicity dependence of the Cepheid period–luminosity (PL) relation is of importance in establishing the extragalactic distance scale. Aims. The aim of this paper is to investigate the

Structure and kinematics of Type II Cepheids in the Galactic bulge based on near-infrared VVV data

Context. Type II Cepheids (T2Cs) are radially pulsating variables that trace old stellar populations and provide distance estimates through their period-luminosity (PL) relation. Aims. We trace the
