PopStar: A new grid of Evolutionary Synthesis Models in the Virtual Observatory

TL;DR

PopStar introduces a comprehensive grid of evolutionary synthesis models for stellar populations, utilizing recent evolutionary tracks and advanced atmosphere models, accessible via Virtual Observatory tools.

Contribution

It provides a new set of models covering wide age and metallicity ranges, integrating latest stellar atmosphere models for hot stars, and accessible through VO.

Findings

Models cover extensive age and metallicity ranges.

Incorporates NLTE atmosphere models for hot stars.

Available in VO format for easy access.

Abstract

We present a new set of theoretical evolutionary synthesis models, PopStar. This grid of Single Stellar Populations covers a wide range in both, age and metallicity. The models use the most recent evolutionary tracks together with the use of new NLTE atmosphere models for the hot stars (O, B, WR, post-AGB stars, planetary nebulae) that dominate the stellar cluster's ionizing spectra. The results of the models in VO format can be used through VOSpec.
