Most Mass-Dependent Isotope Fractionation is Due to Stellar Evolution (Planet Formation)

Authors: Jeffrey Joseph Wolynski

Isotope fractionation means the separation of specific isotopes of a specific element. Say, O-17 is heavier than O-16 so it will sink easier into a star because it is heavier. This is mass dependent isotope fractionation. Most isotope fractionation taught by mainstream only include mass independent fractionation, meaning they are searching for separation of isotopes without mass being a factor. In this paper it is explained firstly that lighter isotopes can escape the star, leaving heavier ones to sink. This leads to the idea that the large percentage of a galactic bodies' isotope fractionation is due to its evolutionary history, and is directly based on mass dependent fractionation. Explanation is provided.
