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.
The concept of life forms living on the surface of neutron stars was proposed by radio astronomer Frank Drake in 1973. Drake said that the atomic nuclei in neutron stars have large variety which might combine in supernuclei, analogous to the molecules that serve the base of life on Earth.

Neutron stars are known that have rotation periods from about 1.4 ms to 30 s. The neutron star's density also gives it very high surface gravity, with typical values ranging from 10 12 to 10 13 m/s 2 (more than 10 11 times that of Earth). [21]
The most dangerous phase in a star's life for potentially habitable planets orbiting it would be the earliest, between the star's formation and its 500 Mya-milestone, especially emphasized (again) on the more massive side of the F-star spectrum. The study even concludes that in some cases (i.e. a planet at the outer edge of the habitable zone ...
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.
A mysterious radio blast from space detected in 2022 originated in the magnetic field of an ultra-dense neutron star 200 million light years away.. Known as fast radio bursts, or FRB, such brief ...
The researchers discovered that while humans have gained about 30 years of life expectancy over the 20 th century, improvements in overall life expectancy have slowed—and actually declined in ...
