A neutron star is 2 solar masses compressed into a ball only 12 kilometers wide. Its surface gravity is so immense it compresses atoms and molecules into raw nuclei and squeezes electrons into protons transforming them into neutrons. Given such immense pressures and densities, you might assume neutron stars have an almost perfectly smooth surface. But you'd be wrong because we know that neutron stars can have mountains.
. 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. To get an idea of what this might be, the authors look at worlds we know, such as Mercury and Enceladus. Their work is published on theThe interiors of Mercury and Enceladus compared.
Mercury, for example, has a thin crust over a large metallic core and has lobate scarps. 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. Othersuch 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.

Researchers discover gravitational collapse and accretion flows in hub filament system G323.46-0.08Hub-filament systems are ubiquitous in molecular clouds. Most dense clumps and cores are formed in filaments and play a key role in star formation process. Therefore, investigating hub-filament system is one of the best ways to understand high-mass star formation.
