Ratio between the Xu et al. (2013) rates, multiplied by a given factor as done in Sect. 8, and the recommended rates from deBoer et al. (2017), with their uncertainties indicated by the blue regions. Temperatures are typical of a core of a CHeB star. To represent the deBoer et al. (2017) rates, we used the tables with update temperature resolution from Mehta et al. (2022) and accessible through Chidester et al. (2022). To compute the Xu et al. (2013) rates, we used the JINA Reaclib equation (Cyburt et al. 2010).
