Welcome to Celia Dalou's personal website
My research focuses in the understanding the behavior of volatile elements (H, C and N) during planetary formation combining experimental petrology, vibrational spectroscopy and state of the art analytical techniques.
Carbon and Nitrogen partitioning between silicate melt and Fe metal as a function of fO2, melt composition, pressure, and C content:
The partitioning of C and N can improve our understanding of the delivery and processing of C and N in growing terrestrial planets, from the distribution of these species in circumstellar disks to their partitioning during magma ocean/core formation stages of planetary differentiation.
