Exploring the desert: Thermal characterization of an exposed planetary core
FY 2024-25 · 2025-03-20
Summary
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.

Description (French)
Ce projet observera l’émission thermique de TOI-849 b, l’une des sub-Neptunes les plus intrigantes, avec le JWST. En raison de sa grande masse et de sa température élevée, TOI-849b est une sub-Neptune ultra-dense et ultra-chaude qui est considérée comme le noyau résiduel exposé d’une planète géante, semblable au noyau profond de notre propre Jupiter mais sans l’atmosphère d’hydrogène étendue. Ces observations caractériseront la composition et la structure de la planète et révèleront des informations clés sur sa nature et son évolution. Cela représentera une avancée majeure pour la science de la formation des sub-Neptunes et des planètes en offrant un regard direct auparavant inaccessible sur un noyau planétaire d’une planète géante, permettant des mesures de la structure de température et des abondances.
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.
