论文摘要
在这项研究中，我们独立地测试了由二进制KIC 9472174周围的系外行星的存在，该二进制是由红色矮人和脉动B型分子组成的。 We also present the results of our search for Jupiter-mass objects orbiting near to the eclipsing binary KIC 7975824, which is composed of a white dwarf and type B subdwarf, and the pulsating white dwarf KIC 8626021. The goal is to test analytical techniques and prepare the ground for a larger search for possible substellar survivors on tight orbits around post-common envelope二进制和恒星在进化的末端，即延伸的水平分支星星和白色矮人。因此，我们主要集中于在宿主以前的红色巨型或渐近巨型相位信封范围内绕这些恒星旋转的实体体。由于我们使用的方法，该任务仅限于单脉冲的B型细分和白矮星和白色矮星，以及含有白色矮人或一个细分布组件的短期黯然失色的二进制文件。 结果。基于本文研究的三个对象，我们证明这些方法可用于检测围绕脉动的白色矮人或B型bubdwarf恒星绕的巨型系外行星以及短期二进制系统，在距离内，距离属于前红色的单星或普通型象征的前红色巨型内心或b invelope的范围内。使用我们的分析技术，我们拒绝在文献中先前提出的距离和轨道时期，围绕二元KIC 9472174围绕二元KIC 9472174的木星质量系外行星的存在。我们还发现，在二进制中观察到的日食定时变化可能取决于开普勒数据的减少和处理。在这项工作中分析的其他两个对象没有从它们的0.7-1.4 au绕的木星质量系外行星，也没有更近轨道上的较大质量对象（给定的质量限制为最小质量）。
In this study, we independently test the presence of an exoplanet around the binary KIC 9472174, which is composed of a red dwarf and a pulsating type B subdwarf. We also present the results of our search for Jupiter-mass objects orbiting near to the eclipsing binary KIC 7975824, which is composed of a white dwarf and type B subdwarf, and the pulsating white dwarf KIC 8626021. The goal is to test analytical techniques and prepare the ground for a larger search for possible substellar survivors on tight orbits around post-common envelope binaries and stars at the end of their evolution, that is, extended horizontal branch stars and white dwarfs. We, therefore, mainly focus on substellar bodies orbiting these stars within the range of the host's former red-giant or asymptotic-giant phase envelopes. Due to the methods we use, the quest is restricted to single-pulsating type B subdwarf and white dwarf stars and short-period eclipsing binaries containing a white dwarf or a subdwarf component. Results. Based on the three objects studied in this paper, we demonstrate that these methods can be used to detect giant exoplanets orbiting around pulsating white dwarf or type B subdwarf stars as well as short-period binary systems, at distances which fall within the range of the former red-giant envelope of a single star or the common envelope of a binary. Using our analysis techniques, we reject the existence of a Jupiter-mass exoplanet around the binary KIC 9472174 at the distance and orbital period previously suggested in the literature. We also found that the eclipse timing variations observed in the binary might depend on the reduction and processing of the Kepler data. The other two objects analyzed in this work do not have Jupiter mass exoplanets orbiting within 0.7 - 1.4 AU from them, or larger-mass objects on closer orbits (the given mass limits are minimum masses).
