论文摘要
在2020年6月4日（Arxiv：1905.09038V2）发现类似地球的行星候选koi-456.04之后，我们已经搜索了与开普勒160系统相关的人工无线电发射。我们的搜索针对的是窄带（2.97 Hz）漂移（$ \ pm 4 $ hz s $^{ - 1}）$和使用turboseti（ARXIV：1709.03491V2）和Spandak Pipelines的宽带脉冲（在所有带宽为5 ms）（所有带宽）的技术签名。在窄带发射的上限上等效的各向同性辐射功率（EIRP）为$ 5.9 \ times 10^{14} $ W，对于窄带排放和$ 7.3 \ times 10^{12} $ W，对于宽带排放，未确定候选者。在这里，我们简要描述了我们的观察和数据减少程序。
We have conducted a search for artificial radio emission associated with the Kepler-160 system following the report of the discovery of the Earth-like planet candidate KOI-456.04 on 2020 June 4 (arXiv:1905.09038v2). Our search targeted both narrowband (2.97 Hz) drifting ($\pm 4$ Hz s$^{-1})$ and wideband pulsed (5 ms at all bandwidths) artificially-dispersed technosignatures using the turboSETI (arXiv:1709.03491v2) and SPANDAK pipelines, respectively, from 1-8 GHz. No candidates were identified above an upper limit Equivalent Isotropic Radiated Power (EIRP) of $5.9 \times 10^{14}$ W for narrowband emission and $7.3 \times 10^{12}$ W for wideband emission. Here we briefly describe our observations and data reduction procedure.
