Max Planck Simulations Reproduce 6 Chondrite Groups From 1 Dust Trap Beyond Jupiter

A single dust trap just beyond Jupiter could have generated several distinct planetesimal families over roughly 2 million years, matching six groups of carbonaceous chondrites in new Max Planck simulations.
The model says the ring sorted material by time: larger, heat-processed solids were trapped first, while finer fragile dust leaked inward and later became dominant as the supply feeding the trap changed.
The first planetesimals formed about 2.3 million years after the Solar System began, resembling CO and CV chondrites; later stages produced matrix-rich CM and Tagish Lake-like bodies, then CR and CI analogs less than 0.1 million years apart.
Researchers say the result links meteorite lab data more directly to disk physics and suggests one long-lived pressure bump outside Jupiter—not many separate birthplaces—may explain much of carbonaceous meteorite diversity.
The findings also support a broader view that Jupiter-shaped disk substructures helped split carbonaceous from noncarbonaceous reservoirs and may guide interpretation of ringed protoplanetary disks seen around young stars.
Could a single dust trap near Jupiter explain the unique chemistries of all our system's planets?
Can this discovery help us predict which distant star systems might harbor Earth-like worlds?
If Jupiter was a planetary nursery, did Saturn also create its own distinct building blocks?
