Urgent Atomic and Molecular Data Needs for Astronomy and Astrophysics

Aims and scope

What are the most urgent data needs of the astronomy and astrophysics community? What key questions about our Universe are being left unanswered because of a lack of accurate atomic and molecular data?

The analysis of astronomical spectra underpins key areas of astrophysical research including stellar structure, exoplanet properties, nucleosynthesis, the variation of fundamental constants and galactic formation and evolution. However, despite the large investment of time, money and resources in recording spectra of astrophysical objects at unprecedented resolutions, the quantity and quality of the existing laboratory data critical for their interpretation lies far from the current needs of the astronomers. The lack of accurate atomic and molecular data remains the Achilles' heel of astrophysics.

This session will further discussion between astronomers with requirements for atomic and molecular data and experimentalists and theoreticians who can provide that data. Closer integration and knowledge transfer between the astronomy and laboratory astrophysics communities are essential for the continued development of both fields. As a result of this special session, we hope to foster new collaborations for the future, which, through targeted measurements and calculations, will accelerate the rate at which data needs can be met and the most exciting questions about our Universe will be answered.
