    Abstract We evaluate the allowed $$\beta^-$$-decay properties of nuclei with $Z = 8$$–$$15$ systematically under the framework of the nuclear shell model using the valence space Hamiltonians derived from modern ab initio methods, such as in-medium similarity renormalization group and coupled-cluster theory. For comparison we also show results obtained with fitted interaction derived from chiral effective field theory and phenomenological universal $sd$-shell Hamiltonian version B interaction. We have performed calculations for O $$\rightarrow$$ F, F $$\rightarrow$$ Ne, Ne $$\rightarrow$$ Na, Na $$\rightarrow$$ Mg, Mg $$\rightarrow$$ Al, Al $$\rightarrow$$ Si, Si $$\rightarrow$$ P, and P $$\rightarrow$$ S transitions. Theoretical results for $B(GT)$, $$\log ft$$ values, and half-lives are discussed and compared with the available experimental data.
