摘要

在对食双星中的大质量脉动器进行深入的星震分析时,星震学和经验恒星基本参数测定的综合优势在处理恒星结构和大质量恒星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方面显示出巨大的潜力。本文汇编了一份用 TESS 观测到的食双星系统中大质量脉冲星的综合清单。对光谱型为B0-B3的8055颗恒星样本的TESS光曲线和离散傅立叶变换进行了蚀变和恒星脉动检验,并计算了由此得到的蚀变双星中大质量脉动器子样本的星历表。这个子样本还与现有的大质量脉冲星星表进行了交叉比对。到目前为止,文献中报道的蚀日双星中的β开普勒脉冲星还不到30个。在此,我们公布了食双星中总共 78 个 β Cephei 类型的脉冲星,其中 59 个是新发现的。其中 43 个已被确认,35 个为候选脉冲星。我们的蚀变双星中脉冲大质量恒星样本可以为未来的星震建模提供帮助,从而更好地理解内部混合剖面,并解决大质量恒星的质量差异问题。我们已经开始对一些最有趣的候选样本进行跟踪研究。

β Cephei Pulsators in Eclipsing Binaries Observed with TESS
The combined strength of asteroseismology and empirical stellar basic parameter determinations for in-depth asteroseismic analysis of massive pulsators in eclipsing binaries shows great potential for treating the challenging and mysterious discrepancies between observations and models of stellar structure and the evolution of massive stars. This paper compiles a comprehensive list of massive pulsators in eclipsing binary systems observed with TESS. The TESS light curves and discrete Fourier transforms of a sample of 8055 stars of spectral type B0–B3 were examined for eclipses and stellar pulsations, and the ephemerides of the resulting subsample of massive pulsators in eclipsing binaries were computed. This subsample was also crossmatched with existing catalogs of massive pulsators. Until now, fewer than 30 β Cephei pulsators in eclipsing binaries have been reported in the literature. Here we announce a total of 78 pulsators of the β Cephei type in eclipsing binaries, 59 of which are new discoveries. Forty-three are recognized as definite, and 35 are candidate pulsators. Our sample of pulsating massive stars in eclipsing binaries allows for future asteroseismic modeling to better understand the internal mixing profile and to resolve the mass discrepancy in massive stars. We have already started follow-up work on some of the most interesting candidates.
