The Color-Magnitude Diagram of composite stellar populations
Abstract
The theoretical relation between the number of post main sequence stars from stellar populations and their total mass in investigated. This is used to derive some basic relations between the stellar number counts of stellar populations with an age spread and the star formation history which produced them. The main purpose of this investigation is to offer a guideline for the construction of simulations aimed at reproducing color- magnitude diagrams.
