Observations of Isotope Fractionation in Prestellar Cores: Interstellar Origin of Meteoritic Hot Spot

摘要

Isotopically fractionated material is found in many solar system objects, including meteorites and comets. It is thought, in some cases, to trace interstellar material that was incorporated into the solar system without undergoing significant processing. Here, we show the results of models and observations of the nitrogen and carbon fractionation in proto-stellar cores.
