[meteorite-list] University of Toronto Talk by Christopher Charles Age of the Solar System?

Hi Tett, Roman and all,

Then concluding with the suggestion that CAI's may be much older that 
previously thought, and
that the solar system may also be much older.

Wish I could have heard the talk also. CAI's have been one of the more 
intriguing things found in our solar systems meteorites. It has been 
brought up before that these may have been remnants from first 
generation stars that super nova and form the solar system. I've heard 
an age of about 10 billion years old. After all, iron is a by-product of 
first generation stars but the isotopes have been reset by re-heating. 
Guess the question is where and when did the CAI's form. It has been 
speculated that CAI's are ash from the super nova event (s) that 
generated our solar system. Perhaps the conclusions are changing.
