论文摘要
我报告了使用Diamante Pipeline从Tess全帧图像（FFI）中提取的140万光曲线的新搜索的新搜索结果。数据来自苔丝观察的前两年（1-26），该研究集中在FGKM矮人的样本上，并优化了用于搜索过境行星的恒星。该搜索是在使用盒子拟合最小二乘算法和随机森林分类器的脱落和缝合的多扇区光曲面上进行的。我提出了1160个过境行星候选者的目录，其中842个是新颖的发现。目录中过境机构的中间半径为6.8 r $ _ {\ oplus} $。半径范围从0.8 r $ _ {\ oplus} $到27.3r $ _ {\ oplus} $，而轨道周期的中位数为3.6天，范围从0.19天到197.2天。每个候选人都伴随着验证报告和相应的Diamante Lightcurve。该材料可在CDS，Exofop网站和MAST的Diamante门户网站上找到。
I report the results of a new search for transiting planets on a set of 1.4 million lightcurves extracted from TESS Full Frame Images (FFIs) using the DIAmante pipeline. The data come from the first two years of observations of TESS (Sectors 1-26) and the study is focused on a sample of FGKM dwarf and subgiant stars optimized for the search of transiting planets. The search was performed on the detrended and stitched multi-sector lightcurves applying the Box-fitting Least Squares algorithm and a Random Forest classifier. I present a catalogue of 1160 transiting planet candidates, among which 842 are novel discoveries. The median radius of the transiting bodies in the catalog is 6.8 R$_{\oplus}$. The radii range from 0.8 R$_{\oplus}$ to 27.3R$_{\oplus}$ while the orbital periods range from 0.19 days to 197.2 days with a median of 3.6 days. Each candidate is accompained by a validation report and the corresponding DIAmante lightcurve. The material is available at CDS, on the ExoFOP website and on the DIAmante portal at MAST.
