#SciFi : Ken Macleod's Learning the World with the advancing wave of green stars points up the idea that the Dyson sphere is less a solid structure than an accumulation of habitats, machines etc.
(Sphere might not be the shape either)
Larry #Niven's #NeutronStar short story points up one problem of near-point masses, tidal forces. One's personal #RocheLimit is best avoided.
Niven again, and the #SmokeRing and #IntegralTrees is interesting wrt a neutron star and habitability. -

Understanding mysterious magnetars 🧲 and radio bursts 🌟 with gravitational waves
A flash of radio waves lasting a few thousandths of a second, as bright as millions or billions of stars, and it’s all over: even almost 20 years after their discovery, fast radio bursts remain one of the most mysterious phenomena in our Universe. Scientists believe that neutron stars – very small and extremely dense stellar remnants with huge magnetic fields – emit these bursts.
An international team has now used gravitational waves to study a nearby neutron star that has emitted several radio bursts. The researchers analyzed data from the German-British GEO600 detector to learn more about the origin of these events. Their results contribute to a better understanding of these extreme events and their theoretical description.

An article published in the journal "Nature" reports the identification of the origin of the fast radio burst cataloged as FRB 20221022A linking it to a magnetar-class neutron star, probably emerging from its magnetosphere. A team of researchers used observations conducted with the CHIME radio telescope to identify the origin of this fast radio burst by exploiting the phenomenon of scintillation.
