Item Modelo estadístico para la distribución de materia en discos protoplanetarios(Universidad Pedagógica y Tecnológica de Colombia, 2018) Buitrago Carreño, Nidia Yiseth; Poveda Tejada, NicanorThe planetary systems have their origin in the gravitational collapse of a cloud of gas and dust. Through an accretion process a massive star and a disk of planetesimals are formed orbiting the star. Through statistical considerations a model is obtained which allows to describe the distribution of matter of the star-planetesimal system. The parameters of the model for the solar system, satellites, exoplanets and the HL-Tauri system are determined. It is shown that the radius, eccentricity, energy, angular momentum and orbital inclination of the planetary objects formed take discrete values, depending only on the value of the mass of the star. Unlike other models, the formation of planetary objects is faster.
