Wadhwa Group Ph.D. student Nicole Phelan is first author of a new research paper released in the journal Geochimica et Cosmochimica Acta, titled "A 187Re-187Os, 87Rb-86Sr, highly siderophile and incompatible trace element study of some carbonaceous, ordinary and enstatite chondrite meteorites".
"The focus of the study is to link the variations observed in the HSE abundances and Re-Os isotopes with other isotopic and elemental data to explore the relative roles of sample sizes, terrestrial alteration and parent body processes more fully on chondrite meteorite compositions."
The research detailed in the paper was performed during Phelan's master's degree studies at the Scripps Institution of Oceanography.
Currently a Ph.D. Student in the Wadhwa Group at ASU, Nicole is measuring the Cr and Ti isotope composition of achondrite meteorites to better constrain the formational timeline of rocky bodies in our Solar System. She's particularly interested in using mass-independant isotopic anomalies (eg 50Ti and 46Ti) in carbonaceous chondrites to model the nucleosynthetic reservoirs from which they may have been sourced.
