Session on Mira Stars (part of the 85th Annual Meeting), November 1, 1996
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).
