Impact jetting as the origin of chondrules
Witryna15 sty 2015 · An impact origin for chondrules implies that meteorites are a byproduct of planet formation rather than leftover building material. Discover the world's research … Witrynativity of produced chondrule mass to the impact velocity (e.g., Asphaug et al. 2011). On the other hand, a con-sistent conclusion is drawn from the impact jetting sce-nario that when the impact velocity exceeds 2.5kms−1, about 1 % of the impactor’s mass becomes the progeni-tor of chondrules for both protoplanet-planetesimal and

Witryna18 cze 2015 · All four chondrules define a brief formation interval with a weighted mean age of 4562.49 ± 0.21 Myr, consistent with its origin from the vapor‐melt impact plume generated by colliding planetesimals. Formation in a debris disk mostly devoid of nebular gas and dust sets an upper limit for the solar protoplanetary disk lifetime at 4.8 ± 0.3 Myr. WitrynaChondrules are one of the most primitive elements that can serve as a fundamental clue 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 leads to the formation of …

Witryna14 sty 2015 · Impact jetting as the origin of chondrules. Chondrules are the millimetre-scale, previously molten, spherules found in most meteorites. Before chondrules formed, large differentiating planetesimals had already accreted. Volatile-rich olivine reveals that chondrules formed in extremely solid-rich environments, more …
Witryna1 sie 2014 · The extreme pressures reached during jetting, a process by which material is squirted out from the contact point of two colliding objects, causes melting and vaporization at low impact velocities.
