The expectation maximization algorithm as a powerful tool to solve the stellar membership in open clusters: An application to M67
The EM algorithm is a powerful tool to solve the membership problem in open clusters when a mixture density model overlaping two heteroscedastic bivariate normal components is built to fit the cloud of relative proper motions of the stars in a region of the sky where a cluster is supposed to be.
