Approximately half of all disk galaxies in the universe exhibit bars. It is well-documented that these bars undergo significant evolution with time after their formation. Traditionally, the formation and evolution of bars have been examined through isolated, idealised N-body simulations. However, in reality, bars also evolve in more complex environments influenced by neighbouring galaxies. In this study, we create a sample of closely interacting galaxy pairs that have bars, using the cosmological galaxy formation simulation TNG50. We classify the galaxies into three categories: isolated barred galaxies, barred galaxy pairs, and barred galaxies within groups. Our objective is to use this sample to investigate how environmental factors influence the kinematic properties of the bars, such as their bar pattern speed.
