cds-question@unistra.frglobular-star-clustersvariable-starsinfrared-photometryWe report the result of our near-infrared observations (JHKs) for type II Cepheids (including possible RV Tau stars) in galactic globular clusters. We detected variations of 46 variables in 26 clusters (10 new discoveries in seven clusters) and present their light curves. Their periods range from 1.2d to over 80d. They show a well-defined period-luminosity relation at each wavelength. Two type II Cepheids in NGC 6441 also obey the relation if we assume the horizontal branch stars in NGC 6441 are as bright as those in metal-poor globular clusters in spite of the high metallicity of the cluster.2006MNRAS.370.1979Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/370/1979CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/48 : A catalogue of field type II Cepheids (Harris, 1985)J/AJ/114/341 : Type II Cepheids (Gonzalez+ 1997)J/AJ/128/1748 : VR photometry of type II Cepheids.
