A Search for Very Low-mass Stars and Brown Dwarfs in the Young sigma Orionis Cluster
V. J. S. Bejar, M. R. Zapatero Osorio, R. Rebolo
We present a CCD-based photometric survey covering 870 sq. arcmin in a young stellar cluster around the young multiple star sigma Orionis. Our survey limiting R, I, and Z magnitude…
