model atmospheres

Model atmospheres are detailed computer simulations that represent the outer layers of stars or planets. They help scientists understand how light and other radiation pass through these layers, influencing the star’s or planet’s observed brightness, color, and spectrum. By adjusting factors like temperature, pressure, and chemical composition, these models provide insights into their physical properties. They are essential tools in astrophysics for interpreting astronomical observations, enabling us to learn about celestial objects’ structure, behavior, and evolution without having to directly access them.
