Hello All!

I am sitting in our backyard enjoying both the wonderful sunny weather
and O.R. Norton's Cambridge Encyclopedia of Meteorites. On page 19
("To Touch a star"), you find this:

"Some researchers proposed that these [= noble gas anomalies]
were signatures of isotopes formed in giant stars and carried
by solid grains to the solar nebua and hence to meteorites."


Best regards,

Bernd
