- FUNDAMENTAL PROPERTIES OF BLUE COMPACT AND HIGH SURFACE BRIGHTNESS STAR CLUSTERS IN THE LARGE MAGELLANIC CLOUD M. L. Talavera A. V. Ahumada J. J. Clariá J. F. C. Santos Jr. E. Bica M. C. Parisi Física, Astronomía y Matemáticas Magellanic Clouds Galaxies: star clusters techniques: spectroscopic Foreground reddening values and ages are determined from integrated spectra for a sample of Key Words: g29 blue, compact and high surface brightness Large Magellanic Cloud (LMC) clusters. Cluster reddening values were estimated by using both the template matching method and interstellar extinction maps, while cluster age s were derivedfrom template matching and equivalent width (EWs) methods, respectively. In the this case, empirical age/metallicity calibrations were used together with diagnostic diagrams involving the sum of EWs of selected spectral lines. The derived cluster ages range from - 5 to 800 Myr. In general, a good agreement is found between the results obtained from the two methods. The present cluster sample omplements previous ones in an attempt to provide a spectral library for the LMC with several clusters per age interval. 2009 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57115758046 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.35
