Connecting Cool Dwarfs’ Stellar Chemistry to Exoplanet Structure and Atmospheres

The session is organized into two 90-minute blocks, separated by a 20-minute coffee break.

Block 1 — Star–planet Connection and Interiors (90 min)

State-of-the-art overview of the star–planet chemical connection, with emphasis on precision and systematics for cool-star abundances and planetary composition constraints.

• Invited keynote: Dr. Vardan Adibekyan (25 min + 5 min Q&A)
  Title + Abstract (soon)

• Contributed talks: 5 × (10 min + 2 min)
  Topics may include: abundance systematics in K/M dwarfs, disk fractionation and inheritance, interior-structure constraints from Fe/Mg/Si, and empirical star–planet composition offsets.

Break (20 min)

Block 2 — Host-Star Abundances and Exoplanetary Atmospheres: Connections and Interpretation (90 min)

How atmospheric properties (metallicity, C/O, disequilibrium chemistry) relate to host-star abundances and interior physics in the JWST era.

• Invited keynote: Dr. Luis Welbanks (20 min + 5 min Q&A)
  Title + Abstract (soon)

• Contributed talks: 4 × (10 min + 2 min)
  Topics may include: JWST results and comparative trends, retrieval systematics tied to stellar abundances, and pathways to consistent chemical scales.

• Discussion panel (15 min)
  Moderated audience discussion to identify key uncertainties, priorities for homogeneous analyses, and opportunities for cross-community collaboration.

Note: The detailed speaker list and schedule will be posted here once the submission process has finalized. We expect mid-April.
