We present the results of time-series photometric analysis of 15106 A-K type stars observed by the Kepler space mission. We identified 513 new rotational variables and measured their starspot rotation periods as a function of spectral type and discuss the distribution of their amplitudes. We examined the well-established period-color relationship that applies to stars of spectral types F5-K for all of these rotational variables and, interestingly, found that a similar period-color relationship appears to extend to stars of spectral types A7 to early-F too. This result is not consistent with the very foundation of the period-color relationship. We have characterized 350 new non-radial pulsating variables such as A- and F-type candidate δ$\delta $ Scuti, γ$\gamma $ Doradus and hybrid stars, which increases the known candidate non-radial pulsators in the Kepler field significantly, by ∼20%. The relationship between two recently constructed observables, Energy$\mathit{Energy}$ and Efficiency$\mathit{Efficiency}$, was also studied for the large sample of non-radial pulsators, which shows that the distribution in the logarithm of Energy$\mathit{Energy}$ (log(En)$\log (\mathit{En})$) can be used as a potential tool to distinguish between the non-radial pulsators, to some extent. Through visual inspection of the light curves and their corresponding frequency spectra, we found 23 new candidate red giant solar-like oscillators not previously reported in the literature. The basic physical parameters such as masses, radii and luminosities of these solar-like oscillators were also derived using asteroseismic relations.

开普勒场中 AK 型恒星样本的脉动和自转研究

我们展示了开普勒太空任务观测到的 15106 颗 AK 型恒星的时间序列光度分析结果。我们确定了 513 个新的自转变量，并测量了它们的星斑自转周期作为光谱类型的函数，并讨论了它们的幅度分布。我们检查了适用于所有这些自转变量的光谱类型为 F5-K 的恒星的已确立的周期颜色关系，有趣的是，我们发现类似的周期颜色关系似乎延伸到光谱类型 A7 到早期的恒星。 F也。这个结果与周期颜色关系的基础不符。我们已经表征了 350 个新的非径向脉动变量，例如 A 型和 F 型候选 δ$\delta $ Scuti、γ$\gamma $ 剑鱼座和混合星，这显着增加了开普勒场中已知的候选非径向脉动，增加了~20%。对于非径向脉动的大样本，还研究了最近构建的两个可观测量 Energy$\mathit{Energy}$ 和 Efficiency$\mathit{Efficiency}$ 之间的关系，这表明 Energy$ 的对数分布\mathit{Energy}$ (log(En)$\log (\mathit{En})$) 在一定程度上可以用作区分非径向脉动的潜在工具。通过对光变曲线及其相应频谱的目视检查，我们发现了 23 个新的候选类红巨星类太阳振荡器，该振荡器以前没有在文献中报道过。这些类太阳振荡器的质量、半径和光度等基本物理参数也是利用星震关系推导出来的。
