Stellar evolution and element nucleosynthesis involve a wide range of interacting physical processes whose knowledge is fundamental to understand the astrophysical phenomena. Several nuclear processes hold the keys to many of the most intriguing problems. However, their studies can be challenging and a number of issues can be better understood by means of “indirect methods”, which are alternative and complementary to direct measurements. Among them, the Trojan Horse Method (THM) gives powerful hints to neutron or charged-particle-induced reactions while the Asymptotic Normalisation Coefficient (ANC) is effective to study particle capture reactions. We will review a couple of cases which were recently studied with those methods and define the importance of those reactions in the framework of stellar physics.
