论文摘要
Zwicky瞬态设施已开始发现轨道周期小于1 \，HR的二元系统。与这些来源的高度光度法相结合，现在可以对这些来源进行系统的确认和表征。在这里，我们报告了ZTF J190125.42+530929.5的发现，一个40.6 \，最小轨道时期，黯然失色的双白乳清二元。光度和光谱建模均证实了其性质，估计的倾斜度为$ i = 86.2^{+0.6} _ { - 0.2} \，\ rm度$，以及$ \ textrm {t} _ \ textrm {t} _ \ textrm {fextrm { $ \ textrm {t} _ \ textrm {eff} = 17,600^{+400} _ { - 400} \，k $。该系统增加了越来越多的未来重力波检测器来源列表，并为双重退化型的人口统计学分析做出了贡献。
The Zwicky Transient Facility has begun to discover binary systems with orbital periods that are less than 1\,hr. Combined with dedicated follow-up systems, which allow for high-cadence photometry of these sources, systematic confirmation and characterization of these sources are now possible. Here, we report the discovery of ZTF J190125.42+530929.5, a 40.6\,min orbital period, eclipsing double white-dwarf binary. Both photometric and spectroscopic modeling confirm its nature, yielding an estimated inclination of $i = 86.2^{+0.6}_{-0.2}\,\rm degrees$ and primary and secondary effective temperatures of $\textrm{T}_\textrm{eff} = 28,000^{+500}_{-500}\,K$ and $\textrm{T}_\textrm{eff} = 17,600^{+400}_{-400}\,K$ respectively. This system adds to a growing list of sources for future gravitational-wave detectors and contributes to the demographic analysis of double degenerates.
