Three appear amorphous shape are probably prestellar nature. fourth clump is best defined coldest coincides young stellar object (YSO) 1623. It suggested that this a protostar whose circumstellar material distributed 'cored-apple' envelope. density gradient appears to be centrally heated envelope or isothermal no central heating object. ejection extremely efficient implies global MHD approach infall outflow may required explain youngest sources. few other low-luminosity YSOs make up entirely new class YSOs.
