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 … 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.

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.
