Given that first generation red dwarves would have been sprayed by the supernovae of many larger stars shouldn't we expect them to have many heavier elements on their surfaces as well. Especially given their age.

Just chanced across Dr. Francis' talks while surfing this evening. Australia National is very fortunate to have such an articulate Prof. He definitely has the gift of parsimony, for even a lay person like myself understood every word of his engaging presentations. Thank you.
