Temperature of a neutron star
WebNeutron stars may exhibit conditions and phenomena not observed elsewhere, such as hyperon-dominated matter, deconfined quark matter, superfluidity and superconductivity … Web8 Apr 2024 · They considered the first 10 seconds or so of a baby neutron star's life after its birth in a supernova. The star would be so hot its guts would be molten. For a subset of neutron stars, that fluid would churn enough to set in motion something similar to the roiling dynamos that power magnetic fields inside Earth or the Sun.

WebUnder some circumstances, a star can collapse into an extremely dense object made mostly of neutrons and called a neutron star. The density of a neutron star is roughly 10^14 times as great as that of ordinary solid matter. Suppose we represent the star as a uniform, solid, rigid sphere, both before and after the collapse. The star’s initial radius was 7.0 * 10^5 km … Web8 Apr 2024 · That lower mass limit for a neutron star is thought to be just over one solar mass. The lightest detected so far is just 1.17 times the mass of the Sun. At 77 percent of a solar mass, XMMU J173203.3-344518 isn't merely record-breaking; it's downright confusing. Neutron stars have no business being so petite. ... and surface temperature.
