Our main goals are to get a deeper insight into the evolution and final fates of intermediate-mass, extremely metal-poor (EMP) stars. We also aim to investigate the C, N, and O yields of these stars. Using the Monash University Stellar Evolution code MONSTAR we computed and analysed the evolution of stars of metallicity Z=10^-5^ and masses between 4 and 9M_{sun}_, from their main sequence until the late thermally pulsing (super)asymptotic giant branch, TP-(S)AGB phase.
