Kind: research · Impact: low

## In brief

- The paper studies the static sector of post-Newtonian gravity, where the symmetry of the static interactions is used to construct the two-body potential at any odd order.
- The authors extend this construction to the seventh post-Newtonian (7PN) potential.
- The work is published in a physics journal and is listed with DOI 10.1103/kcxq-7zsk.

## Why it matters

It advances the analytic description of gravitational two-body interactions in the post-Newtonian expansion, a framework used to model compact binary systems such as those observed by gravitational-wave detectors.
