How small are neutron stars
Nettet20. nov. 2024 · Neutron stars are almost undetectable once they have gone through the short-lived (10 million years or so) pulsar phase, so just counting neutron stars isn't going to give an answer. You also can't just count the number of those stars you assume to be progenitors because they were massive, short-lived and hence sample only the last … Nettet16. mar. 2024 · Most neutron stars cram twice our sun’s mass into a sphere nearly 14 miles (22 kilometers) wide, according to a new study. That size implies a black hole can often swallow a neutron star whole.
