BCC0001, Plasma induced
stellar grains thermally annealed in Fe dust.
A piece of a collapsed
Super Nova.
Above left,
crystallized grains shocked and fractured but held in place by their
melted Fe shells and surrounding grains in a tightly bound matrix and
ground mass. and above right, single
sub-mm grains with many anomlies and a complete nucleus are common.
Notice the
unusual nucleated granular material in the Alumina enriched grain above
right.
Above right a single grain
composed of multiple crystallized dust particles and below a larger
view of the same image.
The photomicrograph above shows a
sub mm stellar grain whose varied composition is consistent with the
accretion of dust particles with a flash coagulation and flash
melting of the paricles in place. The round or circular appearance of
the entire grain may indicate a momentum or velocity component or
movement as part
of the formation process.
