Photometric modeling is a research area within astronomy and astrophysics that focuses on simulating the observed brightness of celestial objects, such as stars, planets, and galaxies. This modeling involves taking into account factors such as the object's size, shape, composition, temperature, and distance from the observer, as well as the effects of interstellar dust and other sources of extinction. By creating accurate models of the photometry of these objects, researchers can better understand their properties and behavior, as well as make predictions for future observations.
