Abstract
The spectral and extinction properties of 14 pre-main sequence candidates in the central part of the very young open cluster NGC 6383 were investigated. None of these stars shows evidence for anomalous circumstellar extinction. However, six out of 14 programme stars do show an infrared excess, indicative of the presence of circumstellar dust, heated up by the central star. One of these stars (number 4), also shows Halpha in emission and shows some indications for the presence of circumstellar gas in its spectrum, and might therefore be a newly identified Herbig Ae star.
