摘要

.小行星地震学与食双星建模相结合,在提高大质量恒星内部混合模型的测量或校准的效率方面显示出巨大的潜力。例如,这有助于处理其恒星结构和演化的观测数据与模型之间存在的具有挑战性的神秘差异。本文讨论了我们利用 TESS 观测到的蚀变双星中的 β Cephei 脉动器的发现,这项工作的目的是编制一份蚀变双星中 β Cep 脉动器的综合目录。共报告了 78 个食双星中的β Cep 型脉冲星,其中 59 个是新发现的。在这里,我们还报告了对另外八颗恒星的新分析,这些恒星不在先前提到的工作范围之内。我们报告了食双星中的 6 颗 β Cep 脉动器,其中 5 颗是新发现的,1 颗是对文献中早先提出的候选者的证实。我们的样本为今后对食双星中的大质量脉冲星进行集合小行星地震建模提供了条件,以处理观测数据与模型之间的差异。

Photometric sample of early B-type pulsators in eclipsing binaries observed with TESS
. 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.
