Enhancements of iron-peak elements for G 112-43/44 and three α-poor halo stars in comparison with the [X/Fe] yield distribution (dotted line) calculated by Lach et al. (2020) for a pure helium shell detonation Type Ia SN model. Red symbols refer to data for G 112-43/44, blue symbols to G 4-36, green symbols to BPS CS 22966-43, and cyan symbols to BPS BS 16920-17. The error bars refer to statistical uncertainties in the abundance determinations.
