Synthetic clusters of massive stars to test stellar evolution models

TL;DR

This paper introduces synthetic stellar clusters generated using the Syclist toolbox to facilitate testing and comparison of stellar evolution models with observational data.

Contribution

It presents the use of the Syclist toolbox for creating synthetic clusters based on new Geneva stellar models, aiding model validation.

Findings

Synthetic clusters enable detailed testing of stellar evolution models.

The Syclist toolbox allows efficient interpolation and simulation of stellar populations.

Comparison with observations can be improved using these synthetic clusters.

Abstract

During the last few years, the Geneva stellar evolution group has released new grids of stellar models, including the effect of rotation and with updated physical inputs (Ekstr\"om et al. 2012; Georgy et al. 2013a,b). To ease the comparison between the outputs of the stellar evolution computations and the observations, a dedicated tool was developed: the Syclist toolbox (Georgy et al. 2014). It allows to compute interpolated stellar models, isochrones, synthetic clusters, and to simulate the time-evolution of stellar populations.
