Hello!
I take a look on wikipedia about CAI and chondrules, but I have still some
doubt.

http://en.wikipedia.org/wiki/Calcium-aluminium-rich_inclusion
http://en.wikipedia.org/wiki/Chondrule

What prompted the formation of CAI? and what's caused the formation of
chondurles???
The supernova gave the energy for the formation of CAI and for the collapse
of the solar nebula?
Some other energy source, still unknow, 2 million years later molten the
material which formed the chondrules? But wich type of energy source?

Is correct this time line?

1) supernova
2) few time later CAI formation
3) at the same time collapse of nebula
4) 2My later condrule formation
5) at the same time proto-sun and proto-planetary formation
6) ...

Thanks a lot!

Best regards!
