Radial evolution of deuterium burning objects (hot start accretion). The solid red lines show our own results, whereas the dashed green lines show the results of Burrows et al. (1997). As the t = 0 definition is not the same, the Burrows et al. (1997) results where shifted in time in order to make the phases of deuterium burning coincide. The mass of the objects is indicated in the plots.
