| dc.description | We present the Period-Luminosity relations from 290 Cepheids towards the LMC and 590 Cepheids towards the SMC. The two data sets were obtained using the two wide field CCD cameras of the EROS 2 microlensing survey. We observe a significant slope change of the period-luminosity relation for the SMC fundamental mode Cepheids with periods shorter than 2 days. Many possible experimental biases have been investigated, but none can account for this effect. We also observe different spatial distributions for SMC Cepheids with different ages i.e. periods. Different possible explanations of the slope change are discussed. | |
