Comparison between our models and the ones used in BPASS for the evolution (left) and spectra (right) of stripped stars. We use five example models of stars that lose their envelopes by Roche-lobe overflow initiated early on the Hertzsprung gap and that have initial masses of M_init, 1 = 5.5, 8.2, 12.2, and 18.2 M_⊙ and initial mass ratios of q = M_init, 2/M_init, 1 = 0.8. We show the models we created in orange, yellow, blue, and green, and BPASS models in gray and pale green.
