cds-question@unistra.frstellar-evolutionary-modelsline-intensitiesphotometryWe present new evolutionary synthesis models for Simple Stellar Populations for a wide range of ages and metallicities. The models are based on the Padova isochrones. The core of the spectral library is provided by the medium resolution Lejeune et al. atmosphere models. These spectra are complemented by NLTE atmosphere models for hot stars that have an important impact in the stellar cluster's ionizing spectra: O, B and WR stellar spectra at the early ages, and spectra of post-AGB stars and planetary nebulae, at intermediate and old ages. At young ages, our models compare well with other existing models but we find that, the inclusion of the nebular continuum, not considered in several other models, reddens significantly the integrated colours of very young stellar populations. This is consistent with the results of spectral synthesis codes particularly devised for the study of starburst galaxies. At intermediate and old ages, the agreement with literature model is good and, in particular, we reproduce well the observed colours of star clusters in LMC. Given the ability to produce good integrated spectra from the far-UV to the infrared at any age, we consider that our models are particularly suited for the study of high redshift galaxies. These models are available on the web site http://www.fractal-es.com/SEDmod.htm and also through the Virtual Observatory Tools on the PopStar server.2009MNRAS.398..451Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/398/451CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/398/451https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/398/451http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/398/451https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/398/451https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/398/451http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/398/451GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/398/451/PopStar1Results of models: types of stars, energy, Ionizing photons, H{alpha} and H{beta} lines, synthetic magnitudesrecnoRecord number assigned by the VizieR team.
