论文摘要
我们通过NASA Transing Exoplanet调查卫星（TESS）任务中的全帧图像数据来搜索一条新的管道定制设计的新管道的结果。该管道在对齐和共同添加框架之前，将消除每个像素的基线通量，并沿着合理的轨道路径进行对齐。我们首先通过恢复三个跨纳普族对象的信号来证明管道的性能-90377 sedna（$ v = 20.64 $），2015 bp519（$ v = 21.81 $）和2007 tg422（$ v = 22.32 $） - 均通过沿着已知的Skypected Paths and-dibtledecy pathed paths and-nights couseede couseede couseede couseede ships and ships shipsing ships ships couseede。然后，我们将这种盲目搜索程序应用于苔丝行业18和19的概念验证调查，该调查延伸到北半球的一部分银河平面。我们在目标搜索九个行星和任何以前未知的独立kuiper带对象的目标搜索中，在地理距离处搜索昏暗的物体$ d = 70-800 $ au，该物体可能会在第九个假设上熄灭。如果没有输入轨道信息，我们目前的管道可以可靠地恢复银河平面中遥远的太阳系物体的信号，$ v <21 $且当前距离$ d \ lyssim 150 $ au，我们详细介绍了前进的路径，以在未来的优化中推动这些限制。本文描述的方法将成为对苔丝遥远的太阳系进行全天鹅转移调查的基础。
We present results from a new pipeline custom-designed to search for faint, undiscovered solar system bodies using full-frame image data from the NASA Transiting Exoplanet Survey Satellite (TESS) mission. This pipeline removes the baseline flux of each pixel before aligning and co-adding frames along plausible orbital paths of interest. We first demonstrate the performance of the pipeline by recovering the signals of three trans-Neptunian objects -- 90377 Sedna ($V=20.64$), 2015 BP519 ($V=21.81$), and 2007 TG422 ($V=22.32$) -- both through shift-stacking along their known sky-projected paths and through a blind recovery. We then apply this blind search procedure in a proof-of-concept survey of TESS Sectors 18 and 19, which extend through a portion of the galactic plane in the Northern Hemisphere. We search for dim objects at geocentric distances $d=70-800$ au in a targeted search for Planet Nine and any previously unknown detached Kuiper belt objects that may shed light on the Planet Nine hypothesis. With no input orbital information, our present pipeline can reliably recover the signals of distant solar system bodies in the galactic plane with $V<21$ and current distances $d\lesssim 150$ au, and we elaborate on paths forward to push these limits in future optimizations. The methods described in this paper will serve as a foundation for an all-sky shift-stacking survey of the distant solar system with TESS.
