Estudio de la dinámica de sistemas binarios de cúmulos abiertos con LP-VIsuite: el cúmulo doble de Perseo

Abstract

In this work, we carry out an investigation of the dynamics of the clusters NGC 869 and NGC 884, known as the Double Cluster in Perseus in order to assess possible past or future approaches between them, and its potential impact on Be star formation. LP-VIcode is used to perform the numerical simulations, while the Hydra 2.0 model is used to represent the Milky Way potential. We find that it cannot be ruled out that a maximum approach in the past may have influenced Be star formation, although the maximum probability for this maximum approach corresponds to a future time. We propose to extend this analysis to other double clusters in the literature to gain a broader understanding of their dynamics, and for those harbouring Be stars to assess whether the dynamics of the clusters may have influenced the formation of Be stars.
