Congratulations, Dr. Emilie Dunham!

Congratulations to Dr. Emilie Dunham, who successfully defended her doctoral thesis September 13th! To Be or not to B: Meteoritic Implications for the Galactic Environment of Solar System Formation Short-lived radionuclides (SLRs) once present in the solar nebula can be used to probe the Solar System’s galactic formation environment. Isotopic analyses reveal that the first […]

New titanium isotope paper

In a new paper published in Geochimica et Cosmochimica Acta, PhD Candidate Zack Torrano and co-authors investigate whether the isotope compositions of previously analyzed calcium-aluminum-rich inclusions (CAIs) are representative of CAIs from other chondrites and chondrite groups and, by extension, the broader CAI-forming region in the solar nebula. CAIs are the oldest dated solids formed […]
