摘要

利用盖亚DR3的数据，我们研究了猎户座星云星团（ONC）的天空区域，在那里使用詹姆斯韦伯太空望远镜（JWST）发现了自由行星和具有行星系统的恒星。我们选择了ONC候选恒星，估计了它们属于该星团的概率。利用盖亚DR3恒星的视差，我们确定了ONC与太阳的距离为393±13 pc。分析使我们能够估计出ONC中心选定空间区域内单星和双星的数量，有行星的恒星的数量，以及自由行星的数量。我们的估计表明有可能从数值模拟中获得新的结果。

Orion Nebula Cluster (ONC) and Planetary Systems from Gaia DR3 and JWST Data

Using Gaia DR3 data, we studied the Orion Nebula Cluster (ONC) in the region of the sky where free planets and stars with planetary systems were discovered using the James Webb Space Telescope (JWST). We selected ONC candidate stars for which the probabilities of belonging to the cluster were estimated. Using Gaia DR3 star parallaxes, we determined the distance of the ONC from the Sun to be 393 ± 13 pc. The analysis allowed us to estimate the number of single and binary stars, the number of stars with planets, and the number of free planets in the selected region of space in the central part of the ONC. Our estimates indicate the possibility of obtaining new results from numerical modeling.
