A base of star clusters for stellar population synthesis
(1986) [Artigo de periódico]Integrated spectra of 63 star clusters with 106 yr ≤age ≤ 1.65 1010 yr and -2.1 [Z/Zʘ] ≤ 0.1 are presented in this paper. The useful wavelength range 3780, 7690 Å was split into 70 consecutive windows, 24-190 Å wide. The ... -
Blue magellanic clusters : near-infrared spectral evolution
(1990) [Artigo de periódico]We present new integrated spectra in the range 5600-10000 Å for 28 LMC and 3 SMC young star clusters. We measure the equivalent widths (W) of prominent features and the continuum distribution. The analysis, supplemented ... -
Near-infrared spectral properties of star clusters and galactic nuclei
(1987) [Artigo de periódico]We present CCD spectra with 12.5 A resolution from 6300 to 9700 Å of 30 star clusters covering ranges 106 to 1.65 1010 yr in age, and -2.0 to 0.1 in metallicity, [Z/Zʘ]. As well, 62 galactic nuclei have been observed in ... -
Rapid changes in the integrated light of young star clusters
(1989) [Artigo de periódico]We discuss the occurrence of rapid red phases in the integrated colours of star clusters by comparing a colour evolution model with spectral and broad band UBVK observations in the LMC. The model is computed with a very ... -
Star formation histories in galaxies : confrontation of theory and observation
(1988) [Artigo de periódico]Population synthesis results for galaxy nuclei from Bica (1988) are compared to those derived from the evolutionary method developed by Arimoto and Yoshii (1986). The two different approaches are interfaced by means of ...
