标题： Rotation periods and seismic ages of KOIs - comparison with stars without detected planets from Kepler observations

摘要： 恒星中最难推导的属性之一是它们的年龄。 对于冷却的主序星，可以使用自转年代学关系，从测量的自转周期和赫罗图位置推断恒星年龄。 这些关系对于具有已知年龄的老年、长自转周期恒星来说，校准器很少。 有一个重要的老年开普勒兴趣天体（KOIs）样本，它们既有可测量的表面自转周期，又有精确的星震学测量数据，从而可以准确推导出年龄。 在这项工作中，我们确定类太阳脉动KOIs的年龄和自转周期，以比较有已知行星和没有已知行星的恒星的自转特性，并扩大老年恒星的自转年代学校准样本。 我们使用开普勒光度计光曲线推导恒星表面自转周期，而年龄则通过星震学方法获得，使用星震建模门户，其中将单个模式频率与高分辨率光谱参数相结合。 因此，我们确定了11颗宿主行星恒星的表面自转周期和年龄，所有恒星都超过20亿年。 我们发现，宿主行星恒星表现出与最新年龄-自转模型一致的自转行为，并且与未检测到行星的恒星的自转行为相似。 我们得出结论，这些老年KOIs可以用来测试和校准自转年代学，以及那些不为人知的宿主行星的恒星。 显示英文摘要

摘要： One of the most difficult properties to derive for stars is their age. For cool main-sequence stars, gyrochronology relations can be used to infer stellar ages from measured rotation pe- riods and HR Diagram positions. These relations have few calibrators with known ages for old, long rotation period stars. There is a significant sample of old Kepler objects of inter- est, or KOIs, which have both measurable surface rotation periods and precise asteroseismic measurements from which ages can be accurately derived. In this work we determine the age and the rotation period of solar-like pulsating KOIs to both compare the rotation properties of stars with and without known planets and enlarge the gyrochronology calibration sample for old stars. We use Kepler photometric light curves to derive the stellar surface rotation peri- ods while ages are obtained with asteroseismology using the Asteroseismic Modeling Portal in which individual mode frequencies are combined with high-resolution spectroscopic pa- rameters. We thus determine surface rotation periods and ages for 11 planet-hosting stars, all over 2 Gyr old. We find that the planet-hosting stars exhibit a rotational behaviour that is consistent with the latest age-rotation models and similar to the rotational behaviour of stars without detected planets. We conclude that these old KOIs can be used to test and calibrate gyrochronology along with stars not known to host planets.
