Abstract
The structure and phase transition of a two-dimensional dusty plasma, confined by an anisotropic power-law potential and interacting via a screened Coulomb potential, were investigated using Monte Carlo simulations. The study varied the number of particles (), screening strength (), eccentricity parameter (), and confinement power parameter () to characterize the system's structural properties. According to the simulation results, the melting temperature is influenced by the eccentricity parameter. Reducing the eccentricity results in a corresponding decrease in the melting temperature. However, the confinement power parameter does not appear to have any impact on the melting temperature.
