Contribution

It advocates for a unified approach to discussing elemental importance across disciplines to enhance planetary habitability research and mission planning.

Findings

Highlighting the need for interdisciplinary communication

Identifying key elements affecting planetary habitability

Proposing a collaborative framework for future research

Abstract

Stellar elemental abundances direct impact planetary interior structure and mineralogy, surface composition, and life. However, the different communities that are necessary for planetary habitability exploration (astrophysics, planetary science, geology, and biology) emphasize different elements. If we are to make progress, especially in view of upcoming NASA missions, we must collectively broaden our communication regarding lists of useful elements, their impact on planetary systems, and how they can be observed in the near and long term.
