论文摘要
脱落的二进制组是用于测量恒星精确质量和半径的主要工具。在以前的论文中，估计了30,000多个脱落的二进制文件的参数，我们确定了766个黯然失色的二进制文件，它们在其全面自动化的Supernovae（ASAS-SN）和过境外部外球体调查卫星（TESS）轻曲线中具有其他特征。在这里，我们表征了这些“外体物理”系统，并识别出斑点恒星，脉动组件和候选三重/四倍系统的二进制系统。我们使用Gaia，Atlas，ZTF和ASAS-SN变量目录来考虑可能的混合物。我们使用雾等等和进化轨道来识别具有主要序列，次级和巨型初选的系统，并突出显示颜色 - 磁性图的稀疏区域中的系统。我们发现，斑点二进制文件的轨道周期分布被进化状态分开，并找到68个带有X射线检测的状态。对于候选三倍/四倍体和脉动系统，我们计算出额外的轨道/脉动周期，并识别具有共振的系统。最后，我们重点介绍了许多外来系统，包括用磁盘黯然失色的CV，细分和二进制文件。
Detached eclipsing binaries are the primary tool used to measure precise masses and radii of stars. In our previous paper estimating the parameters of more than 30,000 detached eclipsing binaries, we identified 766 eclipsing binaries with additional features in their All-Sky Automated Survey for Supernovae (ASAS-SN) and Transiting Exoplanet Survey Satellite (TESS) light curves. Here, we characterize these "extra-physics" systems, identifying eclipsing binaries with spotted stars, pulsating components, and candidate triple/quadruple systems. We use the Gaia, ATLAS, ZTF, and ASAS-SN variable star catalogs to consider possible blends. We use MIST isochrones and evolutionary tracks to identify systems with main sequence, subgiant, and giant primaries and highlight systems in sparsely populated regions of the color-magnitude diagram. We find that the orbital period distribution of spotted binaries is divided by evolutionary state and find 68 with X-ray detections. For the candidate triple/quadruples and pulsating systems, we calculate the extra orbital/pulsational period and identify systems with resonances. Finally, we highlight a number of exotic systems, including eclipsing CVs, subdwarfs, and binaries with disks.
