We present post-processing s-process calculations for the core He-flash of a 1M☉ star with and Z = 10−8. Our model shows neutron densities larger than 1014cm−3, resulting in the production of s-process elements. The model reproduces the C, O, Sr, and Ba abundances of the star hyper metal-poor star HE0107-5240 within a factor of 4.
