Title:
Exploring the desert: Thermal characterization of an exposed planetary core
Agreement Number:

Agreement Date:
Mar 20, 2025 - Mar 1, 2027
Description:
This project will observe the thermal emission of TOI-849 b, one of the most intriguing sub Neptunes, with JWST. Because of its large mass and its high temperature, TOI-849b is an ultra-dense and ultra-hot sub-Neptune which is thought to be the exposed remnant core of a giant planet, akin to the deep interior of our own Jupiter but without the extended hydrogen atmosphere. These observations will characterize the composition and structure of the planet and reveal key insights into its nature and evolution. This will represent a major step for sub-Neptune and planet formation science by giving a previously unobtainable direct look at a planetary core of a giant planet, enabling abundance and temperature structure measurements.
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.
