Efficient mixing of the solar nebular from uniform Mo isotopic composition of meteorites

Article Abstract:

Research has been conducted on meteorites' molybdenum isotopic composition. The authors demonstrate that molybdenum istopic data for differentiated and primitive meteorites show no resolvable deviations from terrestial molybdenum, and suggest that mixing of gas and dust in solar nebular is induced by magnetohydrodynamic instabilities.

Spin control for asteroids

Article Abstract:

The scientists suggest that the collisions between asteroids tilt their spin axes in different directions. The thermal re-radiation recoil force may bring asteroids' spin axes into alignment.
