收藏资源简介:
Gaia DR3食双星候选体数据集包含2,184,477个变星,这些候选体由ESA Gaia任务的可变性处理流程识别,提供轨道周期、光变曲线模型参数和多波段测光数据(G、BP、RP波段)。食双星是指其轨道平面与我们的视线对齐的双星系统,当一颗星从另一颗星前面经过时,会导致周期性的亮度下降。Gaia的全天测光巡天通过自动可变性分类和基于傅里叶的光变曲线建模来识别这些候选体。`global_ranking`分数(0-1)表示一个源是真正食双星的置信度。
Gaia DR3 eclipsing binary candidates — 2,184,477 variable stars with orbital periods, light-curve model parameters, and photometry from ESA Gaia mission. Eclipsing binaries are pairs of stars whose orbital plane is aligned with our line of sight, causing periodic brightness dips as one star passes in front of the other. Gaias all-sky photometric survey identified these candidates through automated variability classification and Fourier-based light-curve modeling. The `global_ranking` score (0-1) indicates the confidence that a source is a genuine eclipsing binary.
