Asteroseismology Meets Art: The beautiful échelle diagram

Since its introduction by Grec et al. (1983), the échelle diagram has proved to be an amazingly useful tool for helio- and asteroseismology. We present an artistic poster that highlights the beauty and usefulness of échelle diagrams. This artwork was produced to hang alongside other physics-themed posters on the walls of the School of Physics at University of Sydney. We provide a link for those who wish to download and print their own copies.
