Daniel, I stumbled upon the D/H ratio stuff and it occurred to me. They cannot have D/H ratios applied to the youngest stars (sun-like and hotter), because those are suppose to be as old as Earth.

So if you see any claims of the D/H ratio being used to date stars that have sun-like masses (as measured against the Earth's D/H ratio), let me know. Chances are you won't. Its worth a shot to see if one of the academics proposed it, yet was peer reviewed out of existence. It would be a rare paper for sure.

So far the D/H ratio being used to date the stars doesn't exist, because astronomers confuse planets as being mutually exclusive to stars. I mean they have the Sun as being >4.5 billion years old. That's really bad, because its 1* 10^-7 ratio is completely ignored. Ouch. Great data being pushed out of the way due to dogma. I told Baz about that and he's happy we finally have a method for dating the youngest stars.
