The neutron star equation of state encodes information about the structure of a neutron star and thus tells us how matter behaves at the extreme densities found inside neutron stars. Constraints on the neutron star equation of state would then provide constraints on how the strong force of the standard model works, which would have profound ...
The habitability of neutron star systems is the potential of planets and moons orbiting a neutron star to provide suitable habitats for life. [1] Of the roughly 3000 neutron stars known, only a handful have sub-stellar companions. The most famous of these are the low-mass planets around the millisecond pulsar PSR B1257+12.

Protons, a more stable particle, have long life spans, to the order of 10 to the power of 32 years, Singh said. Neutrons, on the other hand, live only an average 15 minutes.
The main trait that sets magnetars apart from other neutron stars is a magnetic field 1,000 to 10,000 times stronger than an ordinary neutron star's magnetism and a trillion times that of the sun.
Zooming to RX J1856.5−3754 which is one of the Magnificent Seven and, at a distance of about 400 light-years, the closest-known neutron star. Neutron stars are the collapsed cores of supergiant stars. [1] They are created as a result of supernovas and gravitational collapse, [2] and are the second-smallest and densest class of stellar objects ...
While humans may eventually be able to colonize any kind of stellar habitat, this section will address the probability of life arising around other stars. Stability, luminosity, and lifespan are all factors in stellar habitability. Humans know of only one star that hosts life, the G-class Sun, a star with an abundance of heavy elements and low ...
In astrophysics, the nuclear timescale is an estimate of the lifetime of a star based solely on its rate of fuel consumption. Along with the thermal and free-fall (aka dynamical) time scales, it is used to estimate the length of time a particular star will remain in a certain phase of its life and its lifespan if hypothetical conditions are met.
