Monte Carlo Simulation of Lyα Line Profiles

In this paper, a code for simulating the Lyα line profiles by the Monte Carlo method is introduced. This code is developed on the basis of an idea given by Anne Verhamme et al. and by combining with another simulation method. For different models, the Lyα line profiles under different conditions are simulated. The simulation method of this code is given in detail, and the simulated results are discussed as well.
