Abstract
The spectral and extinction properties of 14 pre-main sequence candidates i n the central part of the very young open cluster NGC 6383 were investigate d. None of these stars shows evidence for anomalous circumstellar extinctio n. However, six out of 14 programme stars do show an infrared excess, indic ative of the presence of circumstellar dust, heated up by the central star. One of these stars (number 4), also shows H alpha in emission and shows so me indications for the presence of circumstellar eas in its spectrum, and m ight therefore be a newly identified Herbig Ae star.
