Cluster resonances in light heavy-ion systems like $^{12}$C+$^{12}$C and $^{12}$C+$^{16}$O may have a major impact on astrophysics stellar scenarios. Resonant radiative capture reactions have been studied for these systems at energies at and slightly below their Coulomb barriers to investigate the possible $^{12}$C-$^{12}$Cand $^{12}$C-$^{16}$O molecular origin of the resonances. Spins have been attributed to the resonances and specificities of their γ-decay have been identified. At deep sub-barrier energies, a fusion cross section measurement using the particle-γ coincidence technique is discussed for the $^{12}$C+$^{12}$C system. A new project is presented to possibly extend the $^{12}$C+$^{12}$C low-energy S factor study.
