Available models for solar metallicity in a Hertzsprung-Russell Diagram. The parameters of the models are the effective temperature (on the x-axis), log (g) (indicated next to the series of models for constant log (g)), the metallicity (fixed to [M/H]=0 in this plot) and stellar mass (color coded) following Husser et al. (2013). The luminosity of the models follows from the given parameters. See Section 4 for a discussion of the shape formed by the available models.
