This paper was written in memory of Joao da Providência who passed away in November
2021. It is a pursuit of works developed recently by Joao, Steven and inspired by our many
years of discussions. Neutron stars are described within the quark–meson coupling
Bogoliubov (QMC Bogoliubov) nuclear model which includes u, d and s quarks. The model
is improved by including the ω-b 3 mixing term so that constraints imposed by ab-initio chiral
effective field theory pure neutron matter calculations are satisfied. The effects of the …
