Abstract: Abstract IAC-pop is a code designed to solve the star formation history (SFH) of a complex stellar population system, like a galaxy, from the analysis of the color-magnitude diagram (CMD). It uses a genetic algorithm to minimize a χ2 merit function comparing the stellar distribution of an observed CMD and the stellar distributions of CMDs arising from linear combination of simple synthetic populations. To this purpose, IAC-star is used to compute a single seminal synthetic CMD from which the simple populations and their corresponding CMD stellar distributions are extracted. In the current version, IAC-pop provides two different estimates of the errors in the SFH. It is offered for free use and can be downloaded from the site www.iac.es/iac-pop.html.

The distribution of low-mass stars in the Galactic disc
TL;DR: In this paper, the authors quantify the complex interdependence of stellar binarity, the stellar mass-luminosity relation, the mass function, the colour-magnitude relation and the Galactic disc structure, all of which must be understood when analysing star-count data and stellar luminosity functions.

TL;DR: A large and updated stellar evolution database for low-, intermediate-, and high-mass stars in a wide metallicity range, suitable for studying Galactic and extragalactic simple and composite stellar populations using population synthesis techniques is presented in this paper.

IAC-STAR: A Code for Synthetic Color-Magnitude Diagram Computation
TL;DR: The IAC-STAR as discussed by the authors code generates synthetic H-R and color-magnitude diagrams (CMDs) and is mainly aimed at star formation history studies in nearby galaxies, by computing the luminosity, effective temperature and gravity of each star by direct bilogarithmic interpolation in the metallicity and age grid of a library of stellar evolution tracks.
