  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.
