From the Sun to Jupiter: Evolution of Low Mass Stars and Brown Dwarfs down to Planetary Masses

Abstract.

We present current models for low mass stars and substellar objects down to planetary masses and discuss the success and remaining uncertainties of the theory. We focus on early evolutionary phases during the first $\sim$ 10 Myr, covering for stars the initial deuterium burning phase to the zero-age Main Sequence. Uncertainties of models at young ages due to the choice of initial conditions are emphasized.
