Evolution of protoplanets growing by pebble accretion
According to recent developments in the planet formation theory, protoplanets form by accretion of small solid particles, known as pebbles, which move through the gaseous media and are decelerated by the aerodynamic drag. Owing to the vigorous material deposition, protoplanets grow rapidly, they become heated and radiate the excessive energy into their surroundings. At the same time, protoplanets migrate due to gravitational interactions with the surrounding disk. I study the evolution of newborn planetary systems while taking into account all the aforementioned phenomena simultaneously, thus providing a realistic feedback between all the system components. Hydrodynamic global-scale simulations are necessary for this purpose.
