That is an interesting article. Thank you for posting it. I wonder if the higher portion of heavy elements means that solar system was created from material that has been through more star creation and death cycles than the material of our solar system.

There's a few possibilities. Initial state is certainly one possibility; another would be a near-miss with another object that resulted in the ejection of a larger amount of lighter elements due to the short term increase in energy in the localized system, and another is that the proximity to the star and constant barrage of solar wind has driven off part of the outermost layers.
We'll probably find out more with additional study. No matter what, it's interesting stuff!
