Deuterium abundance and cosmology (1996)
Vidal-Madjar, A., Ferlet, R., Lemoine, M.
We review the status of the measurements of the deuterium abundance from the local interstellar medium to the solar system and high redshifts absorbers toward quasars. We present preliminary results...

Etangs, A. Lecavelier Des, Vidal-Madjar, A., Ferlet, R.
We have evaluated the spatial distribution of dust in disks supplied by colliding or evaporating bodies spread in a small belt. The gradient of the distribution of dust expelled by radiation pressure...
Beaulieu, J. P., Grison, P., Tobin, W., Pritchard, J. D., Ferlet, R., Vidal-Madjar, A., ...
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 excellent phase...
SEARCH FOR VERY LOW MASS OBJECTS IN THE GALACTIC HALO (1995)
Aubourg, EROS Collaboration: E., Bareyre, P., Brehin, S., Gros, M., Lachieze-Rey, M., Laurent, B., ...
We present results from a search for gravitational microlensing of stars in the Large Magellanic Cloud by low mass objects in the Galactic Halo. The search uses the CCD light curves of about 82,000...

Ansari, R., Cavalier, F., Moniez, M., Aubourg, E., Bareyre, P., Brehin, S., ...
EROS (Exp\'erience de Recherche d'Objets Sombres) has been monitoring the luminosity of 4 million stars in the Large Magellanic Cloud in order to search for gravitational microlensing by unseen...
Spectroscopic Studies of the Two Eros Candidate Microlensed Stars (1994)
Beaulieu, J. P., Ferlet, R., Grison, Ph., Vidal-Madjar, A., Kneib, J. P., Maurice, E., ...
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 Magellanic Cloud....

Beta Pictoris: Back To The Zams
F. Crifo, A. Vidal-Madjar, R. Lallement, R. Ferlet, M. Gerbaldi
According to its new Hipparcos parallax, the star Beta Pictoris is farther away and hence more luminous than previously believed. In the HR diagram, the star is now very close to, or on the ZAMS,...
