  • Recent Kepler observations revealed an abundance of ‘hot’ Earth-size to Neptune-size planets in the inner 0.02–0.2 au from their parent stars. We propose that at least some of these smaller planets are the remnants of massive giant planets that migrated inwards quicker than they could contract. We show that such disruptions occur if the young giant planet embryo is initially extended. The characteristic planet–star separation at which such ‘hot disruptions’ occur is R≈ 0.03–0.2 au. The… CONTINUE READING
