J/MNRAS/397/933 LMC type II Cepheids JHKs magnitudes (Matsunaga+, 2009) ================================================================================ Period-luminosity relations for type II Cepheids and their application. Matsunaga N., Feast M.W., Menzies J.W. =2009MNRAS.397..933M ================================================================================ ADC_Keywords: Magellanic Clouds ; Stars, variable ; Photometry, infrared Keywords: stars: distances - stars: Population II - Cepheids - stars: variables: other - Magellanic Clouds - infrared: stars Abstract: JHKs magnitudes corrected to mean intensity are estimated for Large Magellanic Cloud (LMC) type II Cepheids in the OGLE-III survey the third phase of the Optical Gravitational Lensing Experiment (OGLE). Period-luminosity (PL) relations are derived in JHKs as well as in a reddening-free VI parameter. Within the uncertainties, the BL Her stars (P<4d) and the W Vir stars (P=4 to 20d) are colinear in these PL relations. The slopes of the infrared relations agree with those found previously for type II Cepheids in globular clusters within the uncertainties. Description: S08 (Soszynski et al., Cat. J/AcA/58/293) catalogued 197 CephII variables in the LMC. We searched for near-infrared counterparts in the IRSF catalogue (Kato et al., 2007PASJ...59..615K, Cat. II/288).
