Abstract
Solar-neutrino oscillations are considered using a massive model with perturbative Lorentz violation. The adiabatic approximation is used to calculate the effects of Lorentz violation to leading order. The results are more compact than previous work involving vacuum oscillations, and are accurate for small Lorentz-violating coefficients.
