我们利用2013-2014年16个季度的所有数据，对开普勒数据集中的相位曲线和次日食进行了全面的研究。我们的样本由20颗已确认的行星组成，它们的R p < 4 R e, p < 10 d, V < 15等。在这里，我们得出了它们的温度和反照率，并着眼于约束这些行星形成和演化的模型。在有重叠的地方，我们的结果证实了先前研究得出的参数，而我们对开普勒1b-8b、12b-15b、17b、40b、41b、43b、44b、76b、77b和412b的新结果以一致的方式得出。我们还提供了开普勒91b和开普勒74b的光曲线分析，它们都显示出除了预期的主要和次要日食之外的额外变暗。经热发射校正后，我们发现样本中的大多数大质量行星反照率较低（< 0.1），少数反照率较高（>0.1）。
We present a comprehensive study of phase curves and secondary eclipses in the Kepler data set using all data from 16 quarters that were available in 2013–2014. Our sample consists of 20 confirmed planets with R p > 4 R e , P < 10 d, V mag < 15. Here we derive their temperatures and albedos, with an eye toward constraining models for the formation and evolution of such planets. Where there was overlap our results confirm parameters derived by previous studies, whereas we present new results for Kepler 1b-8b, 12b-15b, 17b, 40b, 41b, 43b, 44b, 76b, 77b, and 412b derived in a consistent manner. We also present light-curve analyses for Kepler 91b and Kepler 74b, which both show extra dimmings at times other than from the expected primary and secondary eclipses. Corrected for thermal emission, we find most of the massive planets from our sample to be low in albedo (< 0.1) with a few having higher albedo (>0.1).
