Astronomers have discovered the gravitational waves released by colliding black holes, neutron stars, and even the background waves from merging supermassive black holes. A new paper proposes that advanced gravitational wave observatories might be able to detect the presence of 'mountains' on spinning neutron stars. Although they're incredibly dense, neutron stars have layers, and as they cool, their solid crusts might deform into regions farther from the central core. This would create a wobble that would release gravitational waves.
The authors start by noting that if a neutron star has a mountain or other deformation that is not axially symmetric, then the rotation of a neutron star would generate gravitational waves. We can’t detect these gravitational waves yet, but future gravitational wave observatories might be able to. They go on to note that the pattern of these gravitational waves will be determined by the distribution and scale of these mountain ranges.

They are likely caused by compression strain as Mercury’s interior cools. Enceladus, on the other hand, has a thin icy crust over an ocean layer and has a “tiger stripe” pattern to its mountains. Other icy moons such as Europa have linear features. Each of these worlds has mountain features driven by the interaction between crust and interior.
One thing the authors found was that if there is a large-scale anisotropy in the crust features of a neutron star, such as the scarps of Mercury, the gravitational waves generated by them could place an upper bound on the rotation speed of neutron stars. While the authors focus on this effect, they also note that the structure of neutron stars may be diverse. Some may have crust features similar to Mercury, while others may have features similar to Europa or Enceladus.
