Abstract:The chondritic building blocks from which Earth formed contain most of their elemental carbon and other volatiles in organic macromolecular matter. This substance is essential to set the chemical composition of terrestrial planets and start the emergence of life, but how it formed is unknown. We demonstrate that this organic macromolecular matter can efficiently form in dust traps – a prominent planet formation mechanism – in the solar nebula. By combining a protoplanetary disk dust evolution model with radiat… Show more
