Leptonic CP violation is one of the most important topics in neutrino physics. CP violation in the neutrino sector is also strongly related to the nature of the neutrino: whether it is a Dirac or a Majorana particle. In this contribution CP-violating effects in Majorana neutrino oscillations in supernova media are studied. We show that resonances in neutrino- antineutrino oscillations induced by strong magnetic fields of astrophysical objects appear in the case of nonzero CP-violating phases. Our findings suggest a potential astrophysical setup for studying the nature of neutrino masses and leptonic CP violation and may be important for future neutrino experiments, for example, such as JUNO and Hyper-Kamiokande.
