Abstract
We have obtained near-IR (NIR) J, H and K mosaic images and photometry of a region 10′×10′ centered on the young pre-main sequence (PMS) star SSV13 in the highly active stars formation region NGC1333-S. The aims of this project are to i) determine the extent and nature of the PMS population in NGC1333-S, ii) investigate techniques to separate embedded PMS stars from reddened background sources, and iii) assess the affect of variable molecular cloud extinction on stellar luminosity functions. Our survey has found 134 sources in NGC1333-S and, from an analysis of the NIR photometry and colours, we conclude that 41 of these objects are probably in a PMS evolutionary state. We class 17 other sources as possible PMS objects. The PMS population is considered consistent with ~5% Class I sources, ~5% Herbig Ae/Be stars, ~25% ‘classical’ T Tauri stars and ~65% young, low-mass stars. Some 10 objects are prime candidates for young, very-low-mass stars.
