J/A+A/xxx/xxx Spectrophotometry of simulated SSPs (J.Schulz, 2002) ================================================================================ Spectral & Photometric Evolution of Simple Stellar Populations at Various Metallicities J. Schulz and U. Fritze - v. Alvensleben and C.S. M\"oller and K. J. Fricke =2002A&A...xxx..xxxK ================================================================================ ADC_Keywords: Clusters, globular ; Clusters, open ; Spectrophotometry ; Colors Keywords: globular clusters: general, open clusters and associations: general, Galaxies: star clusters, Galaxies: evolution Abstract: A new set of evolutionary synthesis spectra are presented for {\bf S}imple {\bf S}tellar {\bf P}opulations ({\bf SSP}s) covering ranges in metallicity from $ 0.02 \leq Z/Z_{\odot} \leq 2.5$ and ages from $4\cdot 10^6$ yr $\leq t \leq 16$ Gyr. They are based on the most recent isochrones from the Padova group that extend earlier models by the inclusion of the thermal pulsing AGB phase for stars in the mass range $2 \, M_{\odot} \leq m \leq 7 \, M_{\odot}$ in accordance with the fuel consumption theorem. We show that with respect to earlier models, inclusion of the TP-AGB phase leads to significant changes in the $(V-I)$ and $(V-K)$ colors of SSPs in the age range from $10^8$ to $\gta 10^9$ yr. Using model atmosphere spectra from Lejeune \etal (\cite{lej2}, \cite{lej}), we calculate the spectral evolution of single burst populations of various metallicities covering the wavelength range from 90 {\AA} through 160 $\mu$m. Isochrone spectra are convolved with filter response functions to describe the time evolution of luminosities and colors in Johnson, Thuan \& Gunn, Koo, HST, Washington and Str\"omgren filters. The models and their results are not only intended for use in the interpretation of star clusters but also for combination with any kind of dynamical galaxy formation and/or evolution model that contains a star formation criterion. Moreover, the evolution of these single burst single metallicity stellar populations is readily folded with any kind of star formation -- and eventually chemical enrichment -- history to describe the evolutionary spectral synthesis of composite stellar populations like galaxies of any type with continuous or discontinuous star formation. For these latter purposes we also present the time evolution of ejection rates for gas and metals for two different {\bf I}nitial {\bf M}ass {\bf F}unctions ({\bf IMF}s) as well as cosmological and evolutionary corrections for all the filters as a function of redshift for $0 \leq z \leq 5$ and two different cosmologies. Description: Spectra, colors and luminosities in various filter-systems as well as cosmological and evolutionary corrections in 2 different cosmologies (H_0=75,\Omega_0=0.1,\Lambda_0=0.9)(H_0=65,\Omega_0=0.1,\Lambda_0=0.0). The total mass in stars of all SPSs are 1.6e9 solar masses at the beginning of evolution. The timestep is 4*10^6 years. the UBV filters are from Buser & Kurucz (1978),the RI filter from Bessell (1990) and JHK from Bessel & Brett (1988). Files are sorted in directorys with following naming-convention: salpeter = SSP with salpeter IMF scalo = SSP with scalo IMF Z1 = 0.0004 Z2 = 0.004 Z3 = 0.008 Z4 = 0.02 Z5 = 0.05 the e- & k-corrections can be found in ek_in_l_75.dat and ek_in_l_65.dat corresponding to the cosmology with H_0=75 and H_0=65 as seen above. Both k-corrections with and without attenuation are included.
