Resumen:
As planets grow, the exchange of angular momentum with the gaseous component of the protoplanetary disc produces a net torque resulting in a variation of the planet?s semi-major axis. For low-mass planets not able to open a gap in the gaseous disc this is known as type I migration. Pioneer works studied this phenomenon in isothermal disc, finding in general fast and inward migration. In the last years several improvements have been made extending the study of type I migration rates to non-isothermal discs. Recently, it was demonstrated that inward migration could be slowed down and even reversed if the planet?s luminosity due to accretion of solids is considered. In this talk we present results of the planet formation process incorporating, and comparing, updated type I migration rates for non-isothermal discs. We also analyse the role of the planet?s luminosity on those rates and its impact on planet formation.
