Following the 2023 Sagan Summer Workshop, there was a half-day workshop to learn about EXCALIBUR (EXoplanet CALIbration and Bayesian Unified Retrieval). EXCALIBUR is a new tool for comparative planetology. Developed at the Jet Propulsion Laboratory, EXCALIBUR implements uniform processing of exoplanet input catalogs with a high-agility architecture to respond to updates in system parameters, observational data, instrument models, and retrieval methods. EXCALIBUR preserves the full chain of inference by saving all intermediate data products. An initial EXCALIBUR catalog and associated data products will be available this summer through a NExScI portal and EXCALIBUR will eventually form the basis of the CASE Explorer Mission of Opportunity data reduction pipeline. The CASE project is the US contribution the European Space Agency's Ariel mission, which will survey the atmospheres of approximately 1000 exoplanets. Hubble data processed by EXCALIBUR has been used to the study the structure, composition, and chemistry of various exoplanet atmospheres (see Swain et al. 2021, Roudier et al. 2021, Estrela et al. 2021, 2022, Huber-Feely 2022).

Full Title: Exoplanet Detection & Characterization in the Ultraviolet Using a Starshade Complement for the Habitable Worlds Observatory
Zahra Ahmed is part of the 2024 NASA ExoExplorers cohort (https://exoplanets.nasa.gov/exep/exopag/exoexplorers/exoexplorers-welcome/), a program that aims to enable the professional development of a cohort of graduate students and/or postdocs in exoplanet research (“ExoExplorers”).
The ExoExplorers program, sponsored by NASA’s Exoplanet Exploration Program Office and the ExoPAG Executive Committee, will focus on the professional development of ~12 graduate student and/or postdoc researchers (“ExoExplorers”) at US and international[1] institutions. Each member of the cohort will be featured in a webinar that will be live-streamed to the exoplanet community, helping to increase their visibility within the field and build internal and external research networks. The cohort will also learn from the experiences of established exoplanet researchers and engineers in the field (“ExoGuides”) via a combination of tailored presentations and small group discussions.
