Building Earth with pebbles made of chondritic components
Susmita Garai, Peter L. Olson, Zachary D. Sharp
Pebble accretion provides new insights into Earth's building blocks and early protoplanetary disk conditions. Here, we show that mixtures of chondritic components: metal grains, ch…

Comment on "Did the terrestrial planets of the Solar System form by pebble accretion?"
Anders Johansen, Peter Olson, Zachary Sharp
Morbidelli, Kleine & Nimmo (2024) (MKN) recently published a critical analysis on whether the terrestrial planets in the Solar System formed by rapid pebble accretion or by the cla…
