Abstract

The DANCe project is a ground-based survey aiming to complement the Gaia space mission (i) beyond the satellite's detection limit down to the planetary mass regime, and (ii) in regions of high extinction where Gaia will be completely blind. The DANCe survey provides very deep and high precision astrometry of young stars in nearby star-forming regions that are very often deeply embedded (especially in their cores) with the primary objective of providing a complete census of the stellar and substellar content. In this project we propose to contribute to the DANCe project in some nearby star-forming regions (Taurus, Upper Scorpius and Ophiuchus) by (i) extending the survey to larger areas in these regions, (ii) participating in follow-up observations and (iii) conducting the scientific analysis of the DANCe targets identified in our study. The research activities described here are complementary to the work conducted at IAG/USP, and they allow us to assume a leading role to complement Gaia in the next future. (AU)
