Some massive but compact objects in our Galaxy emit X-Rays, especially when the compact object interacts with a neighboring star. X-Ray signals indicate that very energetic, high-temperature processes are occurring in a distant object. This article describes a study where researchers simulated a population of massive objects, called high mass X-Ray binaries, representing a massive compact object orbiting its neighboring star and interacting with the neighbor in such a way that it emits X-Rays. This simulation can help astronomers better understand how the population of high mass X-Ray binaries in our Galaxy develops and evolves.
