Gaia & 2MASS fitting for Pleiades members

Accurate determination of binary fractions (fb) and mass ratio (q) distributions is crucial for understanding the dynamical evolution of open clusters. We present an improved...精准测定双星丰度（binary fractions, $f_b$）与质量比（mass ratio, $q$）的分布，对于理解疏散星团（open clusters）的动力学演化至关重要。我们提出了一种改进的……
