Classical Cepheids in open clusters in the era of Gaia DR2
  Classical Cepheids in open clusters are key ingredients for stellar
population studies and the characterization of variable stars, as they are
tracers of young and massive populations and of recent star formation episodes.
Cluster Cepheids are of particular importance since they can be age dated by
using the cluster's stellar population to obtain the Cepheid
period-luminosity-age relation. In this contribution, we present the
preliminary results of an all-sky search for classical Cepheids in Galactic
open clusters by taking advantage of the unprecedented astrometric precision of
the second data release of the Gaia satellite. To do this, we determined
membership probabilities by performing a Bayesian analysis based on the spatial
distribution of Cepheids and clusters, and their kinematics. Here we describe
our adopted methodology.
