Integrating Materials Science Techniques into the Study of Planetary Hazes

Xinting Yu

Photochemical produced hazes are prevalent in the atmospheres of planetary bodies in the solar system and could also be ubiquitous in exoplanetary atmospheres. Haze has been shown to affect the thermal structure and dynamics of planetary and exoplanetary atmospheres. It could also be a source of the surface material on planetary bodies and thus get involved in various surface processes. However, many physical and chemical processes involving the haze are unknown due to the lack of knowledge of the haze as a material. Because of its chemical complexity, many of the intrinsic properties of the haze are highly material dependent and currently have large uncertainties in models. At UCSC, I am using laboratory facilities across the campus to characterize cohesive and thermal properties of planetary and exoplanetary hazes. With the measured properties of the haze, I am exploring cloud-haze interactions in planetary and exoplanetary atmospheres, aeolian transport in the outer solar system with organics being the main transporting material, and haze evolution in deep planetary and exoplanetary atmospheres.
