Overview

My Riebe is interested in the origin and processing of volatile elements in the Solar System. During her Ph.D. research, Riebe studied the effects of various processes on noble gases in meteorites. Most of the so called primordial noble gases, which were incorporated into their carriers either prior to or during the formation of the Solar System, are present in carbonaceous matter in meteorites. A better understanding of the origin of carbonaceous matter will also help our understanding of the origin of primordial noble gases.

At DTM, Riebe will focus her research on the origin and formation of extraterrestrial organic matter. In collaboration with researchers at Carnegie and from other institutions, she will investigate if organic matter could have formed locally in the early Solar System, or, if it formed in the interstellar medium. Characteristics of organic matter produced in experiments reproducing conditions in the early Solar System will be compared with those of the most primitive extraterrestrial organic matter available for laboratory studies. Riebe will mainly use in situ isotopic analyses of hydrogen, nitrogen, carbon and, oxygen but will complement these with other analytical techniques.
