Characterization of Carbon Dioxide on Icy Moons: Laboratory Ice Analogues and JWST Observations

Mixed ices of carbon dioxide (CO₂) and water (H₂O), prevalent in cometary nuclei, solar system satellites, and interstellar dust particles, have posed a persistent challenge in understanding the fundamental behaviors of carbon dioxide in these icy environments. Specifically, the intriguing shift in the CO₂...

Optical appearance of ices in planet forming discs

This thesis aims to improve our understanding of the role of ices in planet forming discs, known as protoplanetary discs. Computer models of such discs have been used extensively by the community to understand and predict the observational data. It has always been a challenge to observe ices in the discs and their optical appearance is largely...

Asteroid characterization through serendipitous detection by the Mid-Infrared Instrument on the James Webb Space Telescope

The interest in asteroids is increasing, due to their promising clues on the origin of the Solar System, e.g. their albedos and sizes can provide insight into the protosolar nebula. The new scientific mission scheduled to launch in 2021, the James Webb Space Telescope (JWST), provides an opportunity for observation of asteroids. In this thesis,...
