A Hectospec Spectroscopic Census of Kinematic Members in the Orion Nebula Cluster
We present a comprehensive spectroscopic census of the Orion Nebula Cluster (ONC), based primarily on low-resolution optical spectroscopy obtained with MMT/Hectospec. We derive spectral types, youth indicators, and accretion diagnostics for 1513 stars located in the ONC region, enabling the identifi
