[MGL99] IRS 14 33 , the SIMBAD biblio

We present the first results of a sensitive (K≃17mag) near IR (JHK) imaging survey of a complete IRAS selected sample of Young Stellar Objects (YSO's) belonging to a Giant Molecular Cloud (GMC) located in the Vela Molecular Ridge (VMR). We provide accurate position and photometry for more than 1300 sources, along with the identification of possible NIR counterparts of the IRAS objects. Through near infrared and 1.3mm photometry we have determined the spectral energy distributions of 11 newly discovered Class I sources and possibly one Herbig Ae/Be star. Their bolometric luminosities indicate that they are protostellar objects of intermediate masses (≤10M_☉) with envelopes containing a not negligible fraction of the central condensed matter. Many sources are associated to diffuse emission which hosts multiple systems of point-like objects. Although clustering is well evident, the NIR counterparts of the IRAS sources seem to be single objects and quite often there are more than one source in the field with JHK colours typical of Class I objects. These findings support the fact that in VMR, as well, stars of different masses are sharing the same birthplace.
