| Abstract: | Nucleosynthesis in advection-dominated accretion flow(ADAF) onto a black hole is proposed to be an important role in chemical evolution around compact stars. We investigate the nucleosynthesis in ADAF relevant for a black hole of low mass,different from that of the self-similar solution. in particular,the presence of supersolar metal mass fractions of some isotopes seems to be associated with the known black hole nucleosynthesis in ADAF,which offers further evidence of diversity of the chemical enrichment. |
