论文摘要
来自太空传播望远镜的不间断观察提供了光度的精确度，以检测地面调查错过的小行星的浅层transiss所需的光度精度。 We used data from the Transiting Exoplanet Survey Satellite (TESS) to search for nearby planetary companions in 12 planetary systems with hot Jupiters: HD 2685, Qatar-10, WASP-4, WASP-48, WASP-58, WASP-91, WASP-120, WASP-121, WASP-122, WASP-140, XO-6, and XO-7.我们还基于同质确定的中期时间应用运输时机方法，以搜索可能在已知已知的行星上重力扰动的非传输伴侣。我们在这些系统中没有发现其他行星，直到纳普尼亚地球仪的政权。这种负面结果与统计研究一致，支持高分子迁移是研究的巨型行星到当今观察到的紧密轨道的途径。
Uninterrupted observations from space-borne telescopes provide the photometric precision that is required to detect shallow transits of small planets missed by ground-based surveys. We used data from the Transiting Exoplanet Survey Satellite (TESS) to search for nearby planetary companions in 12 planetary systems with hot Jupiters: HD 2685, Qatar-10, WASP-4, WASP-48, WASP-58, WASP-91, WASP-120, WASP-121, WASP-122, WASP-140, XO-6, and XO-7. We also applied the transit timing method based on homogeneously determined mid-transit times in order to search for non-transiting companions that could gravitationally perturb the already known planets. We found no additional planets in those systems down to the regime of sub-Neptunian globes. This negative result is in line with statistical studies, supporting the high-eccentricity migration as a pathway of the investigated giant planets to the tight orbits observed today.
