论文摘要
作为其较大使命的一部分，突破性的聆听计划正在对附近的恒星进行最彻底的技术签名搜索。此外，突破性的倾听正在与从事NASAS Transiting系外行星调查卫星（TESS）的科学家进行合作，以检查感兴趣的苔丝目标（TOIS）的技术签名目标。在这里，我们提出了$ 1-11 $ \ $ \ textrm {ghz} $无线电技术签名搜索$ 61 $ tess tois在其突破性收听观察期间在Robert C. Byrd Green Bank Telescope的突破性收听期间。我们进行了狭窄的多普勒漂移搜索，最低S/N阈值为$ 10 $，在$ \ pm 4 $ $ $ \ textrm {hz} $ $ $ \ textrm {s} $ $^{ - 1} $的漂移率范围内，并以$ 3 $ \ textrm {hz} $ {我们通过比较跨目标源的节奏的信号来删除射频干扰。干扰清除后，我们的调查中没有剩余的事件，因此在这项工作中未检测到利益的技术信号。该无效结果意味着在L，S，C和X频段，不到$ 52 \ textrm {％} $，$ 20 \ textrm {％} $，$ 16 \ textrm {％} $，分别具有苔丝Tois Tois tois toister time the equivalent time divalent， $ 10^{14} $ $ \ textrm {w} $。
The Breakthrough Listen Initiative, as part of its larger mission, is performing the most thorough technosignature search of nearby stars. Additionally, Breakthrough Listen is collaborating with scientists working on NASAs Transiting Exoplanet Survey Satellite (TESS), to examine TESS Targets of Interest (TOIs) for technosignatures. Here, we present a $1-11$ $\textrm{GHz}$ radio technosignature search of $61$ TESS TOIs that were in transit during their Breakthrough Listen observation at the Robert C. Byrd Green Bank Telescope. We performed a narrowband Doppler drift search with a minimum S/N threshold of $10$, across a drift rate range of $\pm 4$ $\textrm{Hz}$ $\textrm{s}$ $^{-1}$, with a resolution of $3$ $\textrm{Hz}$. We removed radio frequency interference by comparing signals across cadences of target sources. After interference removal, there are no remaining events in our survey, and therefore no technosignature signals-of-interest detected in this work. This null result implies that at L, S, C, and X bands, fewer than $52\textrm{%}$, $20\textrm{%}$, $16\textrm{%}$, and $15\textrm{%}$, respectively, of TESS TOIs possess a transmitter with an equivalent isotropic radiated power greater than a few times $10^{14}$ $\textrm{W}$.
