No. The mass of a neutron star is so compact and the gravity so high that it could never again become a regular star. Besides, neutron stars come from the cores of stars that have already gone nova. All the hydrogen was already fused into heavier elements.
Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
Any two types of star can be gravitationally bound with another for instance you can get neutron-neutron pairs you can get two yellow stars or you can get a red super giant with a normal star so long as they are in gravitational equilibrium any two can be a paired star
Stars may collapse to such a degree, perhaps after a supernova, that, in the core, electrons are squashed into the nucleus, reacting with protons to form neutrons. A star of this collapsed state is called neutron stars.
Not exactly, while a pulsar is a specific type of neutron star (that being a "spinning neutron star") and a binary system is a pair of stars orbiting each other, a pulsar does not need to be part of a binary system. It would be possible, however to have a binary system with one of the pair being a pulsar and the other a neutron star (assumed to be the non-spinning or "normal neutron star" variety).
The smallest stars are called neutron stars.They typically have a diameter of only 12kmthe smallest star is the neutron star from the word "neutron"
There is an upper limit to the mass of neutron stars because if the neutron star is too massive, neutrons would be crushed by the gravity of the neutron star, and the neutron star would collapse into a black hole.
Pulsars are not only a kind of neutron star, they are neutron stars. See related question.
A star that becomes a white dwarf simply does not have the mass to become a neutron star. White dwarfs are the the remnants of a star very similar to our own sun in mass, where it takes a much more massive star to create a neutron star, Like the star Betelgeuse is a prime example of a star that does not have the mass to become a black hole but is massive enough to become a neutron star.
It is still called a neutron star. Depending on how we observe it, it may also be called a pulsar.
Considering neutron stars are about the size of a city, sub giants are much bigger
Neutron stars are formed when stars with more than 8 times the mass of the Sun run out of fuel and explodes as a supernova. After the star explodes, the core of the star remains, the core would then become a neutron star or a black hole. If the core remain is less than 3 times the mass of the sun, it would become a neutron star.
The name "neutron star" some from the fact that the neutron star is mainly composed of neutrons. The gravitational pull of a neutron star is so strong that most matter are crushed into neutrons.
