Impact jetting as the origin of chondrules
Assuming that a model for melt droplet formation in ejecta curtains8 can be extended to droplet formation in jetted material, we calculate the size of chondrules with ejection velocities equal to the impact velocity (Extended Data Fig. 2). However, jetting ejects material at velocities above the impact velocity … Zobacz więcej Droplet size estimates from the splashing model for chondrule formation16 assume that the pv component of specific enthalpy h = q + pv … Zobacz więcej Extended Data Table 1 describes the input parameters used in our iSALE models.

Chondrules are rounded objects typically from 0.1 to 5 mm in diameter, with an average size of roughly 0.4mm. They are made primarily of olivine and pyroxene with the occasional bits of glass and other trace minerals. Based on radioactive dating of Al-26, which is fairly quick and so leads to low levels, we ...
