Impact jetting as the origin of chondrules
Witryna30 cze 2024 · Chondrules - July 2024. Chondrules and matrix from carbonaceous chondrites exhibit complementary nucleosynthetic W isotope anomalies that result from the depletion of a metallic s-process carrier in the chondrules, and the enrichment of this carrier in the matrix.The complementarity is difficult to reconcile with an origin of … 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.

Witrynadisk lifetime. We perform a parameter study and examine how the abundance of chondrules and their formation timing change. We find that the impact jetting scenario generally works reasonably well for Witryna9 wrz 2024 · To examine the effect of Jupiter on chondrule formation directly, we adopt the impact jetting scenario and compute the resulting abundance of chondrules. Our results show that for the case without Jupiter, chondrule formation proceeds in the inside-out manner, following the growth of protoplanets.
