Resumen:
We present a spectroscopic study of the N159/N160 massive star-forming
region south of 30 Doradus in the Large Magellanic Cloud, classifying a
total of 189 stars in the field of the complex. Most of them belong to O
and early B spectral classes; we have also found some uncommon and very
interesting spectra, including members of the Onfp class, a Be
P Cygni star, and some possible multiple systems. Using spectral
types as broad indicators of evolutionary stages, we considered the
evolutionary status of the region as a whole. We infer that massive
stars at different evolutionary stages are present throughout the
region, favoring the idea of a common time for the origin of recent star
formation in the N159/N160 complex as a whole, while sequential star
formation at different rates is probably present in several subregions.
