[N/O] abundance ratios (upper panels) and helium abundance (lower panels) as a function of the total mass of merger remnants predicted by the models of Glebbeek et al. (2013). Symbols represent the evolutionary stages of the parent stars: solid red circles, blue diamonds, and cyan triangles stand for collisions halfway through the main-sequence lifetime (HAMS), at the terminal-age main sequence (TAMS), and at core hydrogen exhaustion (CHEX), respectively. [N/O] values for our presumably single stars are represented with thin and thick horizontal lines for the cooler and hotter samples, respectively, as a function of their typical masses derived with the Geneva (left panels) and Bonn models (right panels). Typical error bars for the DETAIL/SURFACE and CMFGEN analyses are indicated to the left of the diagrams.
