The EROS2 search for microlensing events towards the spiral arms: the complete seven season results

Understand

The EROS-2 project has been designed to search for microlensing events towards any dense stellar field.

• The densest parts of the Galactic spiral arms have been monitored to maximize the microlensing signal expected from the stars of the Galactic disk and bulge.
• 12.9 million stars have been monitored during 7 seasons towards 4 directions in the Galactic plane, away from the Galactic center.
• A total of 27 microlensing event candidates have been found.
