Abstract

After briefly recalling how microlensing surveys can greatly help research on Long Period Variable stars (LPVs), I present examples from two research projects, Etude et Recherche d'Objets Sombres (EROS) and DUO, and give some examples of preliminary data. This paper is essentially based on the theses of P. Grison (Institute d'Astrophysique [IAP], Paris), J.P. Beaulieu (IAP, Paris), C. Alard (Centre d'Analyse d'Images, Paris), and on the Diplome d'Etudes Approfondies of Y. Audior (IAP, Paris).
