Abstract

Among the H II regions of the SMC, N88A is a small nebula of special interest because there are large amounts of dust associated with it. We present and discuss HST WFPC1 images taken in 1993. HST-FOS spectra were also taken that reveal a rich emission line spectrum in the UV. The emission line strengths enabled accurate derivation of physical conditions and CNO abundances in N88A. When compared with abundances of other SMC H II regions, the O/H value derived for N88A is similar, while C and N are marginally higher. We argue that probably most of the dust located between N88A and the observer belongs to the molecular cloud that gave birth to N88A and that is in the process of disruption.
