Published purpose

Following the JWST ERS and Cycle 1 GO Announcement of Opportunity published on June 14, 2021, the CSA is providing funding via a Grant Agreement to the university to conduct their research using the JWST data. The project will monitor K2-141b for three complete orbits of the planet with the MIRI LRS on the James Webb Space Telescope for just under 21 hours of time. These observations will allow measurements the vertical atmospheric structure on the dayside of the planet, to determine the presence of an extended atmosphere via the planet's nightside temperature, and to search for rock clouds that might form as the supersonic winds blowing towards the nightside cool and condense.
