Bubbles to Chondrites
The formation of chondrules and chondrites is still a controversial issue. Our recent experiments of boiling silicate liquids at high temperatures, ~3000K, have urged my colleague and I to suggest a new model for the formation of the planetary materials; their results have been published in two recent papers. Let me introduce our works with an interesting scene of the experiment.
​
The video (real time) shows a laser-heated liquid silicate spewing numerous jet droplets. The droplets emerge from boiling bubbles as they rupture in microseconds. In the video (a field of view ~10x10 cm) the laser beam comes from the upper left corner, and hits the silicate liquid sitting in the middle of the frame. The droplets splash at high speeds, leaving streaks of light. A dense silicate vapor forms around the silicate liquid and immediately condenses as ultra-fine particles, scattering lights like a haze.
