Resumen:
We study the integrated spectral evolution in the blue-violet range of
97 blue star clusters in the Magellanic Clouds, from those associated
with gas emission to those as old as a few hundred Myr. Some clusters
are dominated by the flux of those massive stars that pass through
evolutionary stages such as Wolf-Rayet, Luminous Blue Variable, Be, and
supergiant stars of different temperatures. The relationships among
spectral features such as absorption and emission lines, Balmer
discontinuity and Balmer continuum are used to study the spectral
evolution of the clusters. Finally, we sort into groups spectra of
similar evolutionary stages, creating a template spectral library with
possible applications in stellar populations syntheses of star-forming
galaxies and in the spectral simulation of bursts of star formation with
different mean ages and durations.
