These growing planets undergo accretion heating, which triggers a hot-trail effect that can reverse migration directions, increase eccentricities and prevent resonant captures (Chrenko et al. 2017). We study populations of embryos accreting pebbles using Fargo-Thorin 2D hydrocode.\n  We find that embryos in a disk with high surface density ($\\Sigma_0 = 990\\,{\\rm g}\\,{\\rm cm}^{-2}$) undergo `unsuccessful' two-body encounters which do not lead to a merger.
