Description:
This project aims to perform a full panchromatic characterization of the warm Neptune TOI-674 b (640 K) using JWST, observing both transmission (0.6 – 12 µm) and emission (3 – 5.2 µm) spectra. TOI-674 b is uniquely suited for this dual-geometry study, enabling constraints on aerosol properties, atmospheric chemistry, and thermal structure. The results will break cloud-metallicity degeneracies, probe CH4/CO chemistry, assess potential tidal heating, and reveal formation and migration pathways, establishing TOI-674 b as a benchmark for warm Neptune atmospheres.
Organization:
Canadian Space Agency
Expected Results:
The Research component of the program provides financial support to organizations to conduct space related research and development in priority areas. It will support targeted knowledge development and innovation to sustain and enhance the Canadian capacity to use space to address national needs and priorities in the future.
