H-R diagram showing evolutionary tracks for masses of 0.3, 1.0, 3.0, and 8.0 M from the base grid. We show how each track evolves across metallicities [Fe/H] = −1.0 (solid blue), −0.5 (dashed green), 0.0 (dashed–dotted purple), and +0.5 (dotted gray). The 0.3 M tracks extend to the ZAMS, the 1.0 M tracks to the tip of the RGB, and the 3.0 and 8.0 M tracks to ZAHB, defined by Ycen = 1−Z−0.06.
