FLAMES spectroscopy of low-mass stars in the young clusters σ Ori and λ Ori
Abstract
Aims: We performed a detailed membership selection and studied the accretion properties of low-mass stars in the two apparently very similar young (1-10 Myr) clusters
Methods: We observed 98 and 49 low-mass (0.2-1.0 M⊙) stars in
Results: We identified 65 and 45 members of the
Conclusions: The different disk and accretion properties of the two clusters could be due either to the effect of the high-mass stars and the supernova explosion in the
