Based on simulations of aspherical explosion of core-collapse supernovae (SNe) of massive stars, we investigate abundances of SN ejecta. We find that abundances of ejecta from an SN of a star with the solar metallicity reproduce the solar composition, and that abundances of ejecta from SNe of zero-metal massive stars well reproduce observed abundances of the surface of metal-poor stars. Moreover, from SN simulations employed with newly-developed hydrodynamic code, in which heating via nuclear reactions are taken into account, we show that the nuclear heating are greater than or comparable to neutrino-heating.
