Impact jetting as the origin of chondrules
Witryna15 gru 2024 · The origin of most chondrules (small, previously molten spherules inside meteorites) is shown to be impact jetting; chondrules form from the shock-melted material ejected from a protoplanet on ... 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.

Witryna11 lis 2015 · Chondrules are one of the most primitive elements that can serve as a fundamental clue as to the origin of our Solar system. We investigate a formation scenario of chondrules that involves planetesimal collisions and the resultant impact jetting. Planetesimal collisions are the main agent to regulate planetary accretion that … Witryna1 sty 2015 · This website requires cookies, and the limited processing of your personal data in order to function.

An impact origin for chondrules implies that meteorites are a byproduct of planet formation rather Witryna20 lis 2016 · The formation of chondrules is one of the oldest unsolved mysteries in meteoritics and planet formation. Recently an old idea has been revived: the idea that chondrules form as a result of collisions between planetesimals in which the ejected molten material forms small droplets that solidify to become chondrules.
