Solar neutrino fluxes. The stars and circles show the models with variable and steady Z_accretion, respectively. Orange and brown illustrate the models with and without turbulent mixing, respectively. Blue shows the models from KGB22 (with AGSS09 abundances and without turbulent mixing). The points with error bars are the observational constraints (Table 1). The dotted cyan error bar shows an old constraint from Borexino Collaboration (2020).
