EROS 2 proper motion survey : a field brown dwarf and an L dwarf companion to LHS 102 / EROS Collaboration
We report the discovery of two L dwarfs (the new spectral class defined for dwarfs cooler than the M type) in a two-epoch CCD proper motion survey of 413 square degrees, complemented by infrared photometry from DENIS. One of them has a strong lithium line and is therefore a brown dwarf. [...]

Observation of Microlensing towards the Galactic Spiral Arms : EROS II 2 year survey / EROS Collaboration
We present the analysis of the light curves of 8.5 million stars observed during two seasons by EROS (Experience de Recherche d'Objets Sombres), in the galactic plane away from the bulge. Three stars have been found that exhibit luminosity variations compatible with gravitational microlensing effects due to unseen objects. [...]

AGAPEROS : Searches for microlensing in the LMC with the Pixel Method; 2, Selection of possible microlensing events / Melchior, A.L. (Queen Mary, U. of London ; College de France) ; Afonso, C (CEA, DSM, Saclay ; DAPNIA, Saclay) ; Ansari, R (Orsay, LAL) ; Aubourg, E. (CEA, DSM, Saclay ; DAPNIA, Saclay) ; Baillon, P.

(CEA, DSM, Saclay ; DAPNIA, Saclay) et al.
We apply the pixel method of analysis (sometimes called ``pixel lensing'') to a small subset of the EROS-1 microlensing observations of the bar of the Large Magellanic Cloud (LMC). The pixel method is designed to find microlensing events of unresolved source stars and had heretofore been applied only to M31 where essentially all sources are unresolved. [...]
