Microlensing Optical Depth of the Large Magellanic Cloud
E. Aubourg, N. Palanque-Delabrouille, P. Salati +2
The observed microlensing events towards the LMC do not have yet a coherent explanation. If they are due to Galactic Halo objects, the nature of these objects is puzzling --- half…

EROS VARIABLE STARS : FUNDAMENTAL-MODE AND FIRST OVERTONE CEPHEIDS IN THE BAR OF THE LARGE MAGELLANIC CLOUD
J. P. Beaulieu, P. Grison, W. Tobin +27
We present CCD phase-binned light curves at 490 nm for 97 Cepheid variable stars in the bar of the LMC. The photometry was obtained as part of the French EROS project and has excel…

Spectroscopic Studies of the Two Eros Candidate Microlensed Stars
J. P. Beaulieu, R. Ferlet, Ph. Grison +26
Low resolution spectroscopy, and UBVRI photometry, have been obtained for the two EROS microlensing candidates. Radial velocities indicate that both stars are members of the Large…
