  1. On the Progress of models and simulations of giant planet formation Física del Sistema Solar, 2012Sara Bertrán de Lis

  2. Modelo “Core Accretion” Colapso nube densa gas Protoestrella + disco “coagulación” polvo + colisiones/inest. planetesimales + colisiones protoplanetas = núcleo sólido Pollack et al. 1996 planeta gaseoso planeta terrestre

  3. Modelos extendidos • - Tasas acreción • Ecuaciones estado • Patrones densidad en disco • Opacidad: de MI a granos en envolturas • - Evolución del disco protoplanetario • Migración planetaria (“Hot Jupiters”) Observaciones Síntesis población con simulaciones Monte Carlo Modelos

  4. Modelo extendido + Monte Carlo • - Cociente gas/polvo • Densidad sup. inicial gas • Tasa fotoevaporación • Semieje mayor inicial Parámetros iniciales “cruciales” Distribuciones probabilidad Set Cond. iniciales Parámetros fijos: tamaño disco, fracción helio, datos núcleos, ect. Evol. Temporal y prop. finales • Evol. Estructura vertical disco • Evolución densidad sup. Disco gas • Tasa migración • Evolución planetesimales • Interacción planetesimal – atmosfera protoplanetaria • Estructura y evolución protoplaneta Modelo

  5. Resultados modelo extendido I Mordasini et al. 2009

  6. N-body + disk model Thommes et al. 2008

  7. MESS: Multi-purpose Exop Simulation System Bonavita et al. 2011
