Meteorites, Bipolar Jet Flows and Relativistic MHD - Kurt Liffman Colloquium
Primitive meteorites are not only samples of asteroids and comets, but are also fossilized samples of the solar nebula - the disk of gas and dust that once surrounded the Sun. Many such meteorites contain small, millimetre-sized, igneous objects called chondrules and "CAIs" surrounded by a dark sedimentary-like substance called "matrix". The matrix has never experienced temperatures in excess of 600 K, but the chondrules and CAIs were formed at temperatures in excess of 1800 K. How such material could have formed in the solar nebula has been a subject of scientific speculation for over two centuries.
