L-band (3.5 mu m) IR-excess in massive star formation I. 30 Doradus
L-band data of 30 Doradus at 3.5 mu m taken with SPIREX (South Pole Infrared Explorer) is presented. The photometry was combined with 2MASS JHK data at 1.25- 2.2 mu m. Colour-colour and colour-magnitude diagrams are constructed and used to determine the sources with infrared excess. These are interp...
