Images of (a) dust particle Kenneth from comet 67P/Churyumov-Gerasimenko, collected by the COSIMA instrument on board the Rosetta spacecraft, (b) an Interplanetary Dust Particle (IDP) collected in the stratosphere and (c) an UltraCarbonaceous Antarctica MicroMeteorite (UCAMM) collected in Antarctic snow. Some IDPs and UCAMMs are thought to originate from comets. Credits: Images are modified after (a) Fray et al. (2016), (b) Brownlee D. E. (2016) and (c) Engrand et al. (2016).

Anaïs Bardyn is interested in the study of cometary organic matter. Comets are among the most pristine bodies within the Solar System, their composition and their organic content provide insight into conditions of the formation and early evolution of the Solar System.

During her Ph.D. research, she worked on the characterization and quantification of the refractory organic matter in comet 67P/Churyumov-Gerasimenko’s particles by mass spectrometry with the COSIMA instrument on board the Rosetta spacecraft.

At DTM, she plans to conduct in-depth analyses of collected extraterrestrial particles by a complementary suite of micro-analytical techniques. The particles are directly collected from the clean Antarctic air in the South Pole station. Pristine and primitive extraterrestrial materials are expected to be collected, some of them could originate from comets. Another part of her postdoctoral research at DTM will be to compare the composition of the particles with the in situ data from comet 67P/Churyumov-Gerasimenko acquired by the COSIMA instrument. The comparison between these two sets of unique data could lead to evidence and/or confirmation of the potential cometary origin for some of the particles collected from the Antarctic air.
