论文摘要
当验证对流在恒星进化模型中的作用时，具有低质量成分的脱落要的二进制文件的表征变得很重要，这需要对恒星参数的模型独立的测量，并具有很高的精度。然而，光谱表征取决于单目标径向速度观测值，并且仅以这种方式诊断出了几十个研究的低质量系统。我们通过采用纯粹的光度计方法来表征{\ it Kepler}字段的黯然失色的系统。基于广泛的多色数据集，我们使用群集技术得出了有效的温度和单个组件的光度质量质量。我们还通过可用{\ it kepler}光曲线的其他建模来估算出恒星半径。我们的测量结果证实了质量 - 拉迪乌斯图中针对低质量制度中理论恒星模型的通胀趋势。
The characterisation of detached eclipsing binaries with low mass components has become important when verifying the role of convection in stellar evolutionary models, which requires model-independent measurements of stellar parameters with great precision. However, spectroscopic characterisation depends on single-target radial velocity observations and only a few tens of well-studied low-mass systems have been diagnosed in this way. We characterise eclipsing detached systems from the {\it Kepler} field with low mass components by adopting a purely-photometric method. Based on an extensive multi-colour dataset, we derive effective temperatures and photometric masses of individual components using clustering techniques. We also estimate the stellar radii from additional modelling of the available {\it Kepler} light curves. Our measurements confirm the presence of an inflation trend in the mass-radius diagram against theoretical stellar models in the low-mass regime.
