A Method to Fit Phase Diagrams of Slow-Rotation Pulsars with Accretion Columns

We demonstrate a method to simulate pulse profile of the emission accretion columns in neutron star. Given set parameters that characterize star, e.g., mass and radius, positions shapes columns, can be calculated compared with real data. Some characteristics phase diagrams are shown considering an column form cone trunk also cylinder. Furthermore, our first approach we develop combination between genetic algorithm Bayesian sampling constrain some variables. Finally, as example, apply observed data source 1A 0535+262.
