From fraser@m.universetoday.com on Mastodon: If Neutron Stars Have Mountains, They Should Generate Gravitational Waves 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. # gravitationalwaves http:// arxiv.org/abs/2309.04855
