On biases in the predictions of stellar population synthesis models
Sampling fluctuations in stellar populations give rise to dispersions in observables when a small number of sources contribute effectively to the observables. This is the case for a variety of linear functions of the spectral energy distribution (SED) in small stellar systems, such as galactic and extragalactic HII regions, dwarf galaxies or stellar clusters. In this paper we show that sampling...
متن کاملStellar population synthesis diagnostics
A quantitative method is presented to compare observed and synthetic colour-magnitude diagrams (CMDs). The method is based on a χ merit function for a point (ci,mi) in the observed CMD, which has a corresponding point in the simulated CMD within nσ(ci,mi) of the error ellipse. The χ merit function is then combined with the Poisson merit function of the points for which no corresponding point wa...
متن کاملHow binary interactions affect stellar population synthesis
The single star-stellar population (ss-SSP) models are usually used for stellar population studies. However, there are more than 50% stars that are in binaries and evolve differently from single stars. This suggests when we model the stellar populations of galaxies and star clusters, the effects of binary interactions should be considered. Although a few works tried to model stellar populations...
متن کاملA Large Stellar Evolution Database for Population Synthesis Studies. I. Scaled Solar Models and Isochrones
We present a large and updated stellar evolution database for low-, intermediateand high-mass stars in a wide metallicity range, suitable for studying Galactic and extragalactic simple and composite stellar populations using population synthesis techniques. The stellar mass range is between∼ 0.5M⊙ and 10M⊙ with a fine mass spacing. The metallicity [Fe/H] comprises 10 values ranging from −2.27 t...
متن کاملSimple stellar population models including blue stragglers
Observations show that nearly all star clusters and stellar populations contain blue straggler stars (BSs). BSs in a cluster can significantly enhance the integrated spectrum of the host population, preferentially at short wavelengths, and render it much bluer in photometric colours. Current theoretical simple stellar population (SSP) models constructed within the traditional framework of singl...
