Descripción
The young σ Orionis cluster in the Ori OB 1b association is one of
the most important clusters for understanding the stellar and substellar
formation and evolution. In this work, we used 197 low-resolution
optical spectra of 167 stars. We determined spectral types and measured
Li I and Hα equivalent widths (EWs). We used Gaia DR2 astrometry
together with youth features indicators from literature to derive the
true membership to the cluster.
