论文摘要
我们提出了用于偏心二进制的啤酒模型的扩展 - ebeer，通过其轨道的开普勒元素的谐波系列近似光束，椭圆形和反射效应。因此，它可以是快速处理光曲线的工具，用于检测非分数偏心二进制系统。为了验证偏心模型及其近似值的适用性，我们将ebeer应用于开普勒光曲线，确定了明亮的非注射二进制候选者的样本，并随后三个与明智的观察者Eshel光谱仪紧随其后。在确认这三个系统的确是径向速度（RV）二进制文件之后，我们将光曲线和RV数据拟合到Phoebe，Phoebe是一个详细的数值光曲线和RV模型，并表明Phoebe派生的参数与Ebeer近似获得的参数相似。
We present an extension of the BEER model for eccentric binaries - eBEER, approximating the BEaming, Ellipsoidal and Reflection effects by harmonic series of the Keplerian elements of their orbit. As such, it can be a tool for fast processing of light curves for detecting non-eclipsing eccentric binary systems. To validate the applicability of the eccentric model and its approximations, we applied eBEER to the Kepler light curves, identified a sample of bright non-eclipsing binary candidates, and followed three of them with the Wise observatory eShel spectrograph. After confirming the three systems are indeed radial-velocity (RV) binaries, we fitted the light curves and the RV data with PHOEBE, a detailed numerical light-curve and RV model, and showed that the PHOEBE derived parameters are similar to those obtained by the eBEER approximation.
