Abstract: Asteroseismology coupled with eclipsing binary modelling shows great potential in improving the efficiency of measurements or calibrations of the interior mixing profile in massive stars. This helps, for instance in treating the challenging and mysterious discrepancies between observations and models of its stellar structure and evolution. This paper discusses the findings in our work titled β Cephei pulsators in eclipsing binaries observed with TESS, which aimed to compile a comprehensive catalogue of β Cep pulsators in eclipsing binaries. Seventy-eight (78) pulsators of the β Cep type in eclipsing binaries among which 59 new discoveries were reported. Here, we also report a fresh analysis of eight additional stars that were outside the scope of the earlier-mentioned work. Six β Cep pulsators in eclipsing binaries are reported, among which 5 are new discoveries and 1 is a confirmation of a candidate earlier suggested in the literature. Our sample allows for future ensemble asteroseismic modelling of massive pulsators in eclipsing binaries to treat the discrepancy between observations and models.
