- Interactions between the planets with the protoplanetary gas disk produce migration, whose rates depend on the features of the gas-disk and the mass of the migrating planets. Due to the uncertainties in the estimations of masses of the TRAPPIST-1 planets, their migration rates are not well determined. In this work, we present A-body simulations including type-I migration, to reproduce the general configuration of the TRAPPIST- 1 system and analyze its multi-resonant state. We found that the circularization timescale, characterized by the Qe eccentricity damping factor, is a critical parameter in reproducing its architecture. When Qe <0.1 the orbit circularizes faster and we are able to find resonance trapping in the 8/5 mean motion resonance between the two innermost planets.
La interacción entre los planetas y el disco protoplanetario produce que éstos migren a una tasa que depende de las características del disco de gas y la masa de los planetas migrantes. Debido a la incerteza en la determinación de las masas de los planetas del sistema TRAPPIST-1, sus tasas de migración no están bien determinadas. En este trabajo presentamos el resultado de simulaciones de A-cuerpos con migración de tipo I para reproducir la configuración general de TRAPPIST-1 y estudiar su estado multiresonante. Encontramos que la escala de tiempo de circularización orbital, caracterizada mediante el factor de decaimiento de la excentricidad Qe, es un parámetro crítico para reproducir su arquitectura. Si Qe < 0.1 la órbita se circulariza más rápidamente y es posible encontrar una captura en la resonancia de movimientos medios 8/5 entre los dos planetas más internos.
