Reassessing Chemical Processes Defining the Isotopic Compositions of the First Solids in the Solar System
The first solids formed in the Solar System record an unusual oxygen isotope signature that is distinct from that of Earth. Their 17O/16O and 18O/16O variations follow a nearly one-to-one relationship, rather than the relationship expected from conventional mass-dependent isotope fractionation. This mass-independent signature provides an important constraint on the physical and chemical environ...

How do you form a solar system like ours?
Our solar system makes it seem like the planets were formed in a nice, ordered disc. But dig a little deeper and there are hints that things are not quite as neat as they seem — spins do not align, dust appears to have been violently melted and the planetesimal disc remains sharply truncated at 47 au. The last 10 years has brought us spectacular observations of planet formation `in action’ in...
