Abstract

We combine new results from the search for microlensing towards the Large Magellanic Cloud (LMC) by EROS2 (Experience de Recherche d'Objets Sombres) with limits previously reported by EROS1 and EROS2 towards both Magellanic Clouds. The derived upper limit on the abundance of stellar mass MACHOs rules out such objects as an important component of the Galactic halo if their mass is smaller than 1 solar mass.<br />4 pages, 2 figures, Accepted by A&A Letters Feb 23, 2000 (minor modifications in section 6)
