High-resolution Study of Planetesimal Formation by Gravitational Collapse of Pebble Clouds
Published 2023-01-01“…The size distribution is top-heavy and can be described with a Gaussian distribution of planetesimal mass. For the asteroid belt, we can infer a most likely size of 125 km, all stemming from pebble clouds of equivalent size 152 km.…”

Initiation of plate tectonics in the Hadean: Eclogitization triggered by the ABEL Bombardment
Published 2018-07-01“…When plate tectonics began on the Earth has been long debated and here we argue this topic based on the records of Earth-Moon geology and asteroid belt to conclude that the onset of plate tectonics was during the middle Hadean (4.37–4.20 Ga). …”

Chondrites as samples of differentiated planetesimals
Published 2017“…Such bodies may exist in the asteroid belt today; the shapes and masses of the two largest asteroids, 1 Ceres and 2 Pallas, can be consistent with differentiated interiors, conceivably with small iron cores with hydrated silicate or ice–silicate mantles, covered with undifferentiated crusts.…”
