A pulsar is a rapidly spinning neutron star that releases regular pulses of electromagnetic radiation from its magnetic field
Pulsars are not only a kind of neutron star, they are neutron stars. See related question.
No, not all neutron stars are pulsars. Pulsars are neutron stars that emit beams of radiation that are detectable from Earth as rapid pulses of light. While many neutron stars are pulsars, not all neutron stars exhibit this pulsing behavior.
No, not all neutron stars are pulsars. Pulsars are a type of neutron star that emits beams of radiation, which can be detected as pulses of light. Some neutron stars do not emit these beams and are not classified as pulsars.
The collapse of massive stars - the same as neutron stars.
Because I am interested in neutron stars.
pulsars
Not all neutron stars are seen as pulsars because pulsars emit beams of radiation that are only visible if they are pointed towards Earth. If a neutron star's beams are not aligned with our line of sight, it will not appear as a pulsar.
Not all young neutron stars are observed as pulsars because pulsars emit beams of radiation that are only visible if they are pointed towards Earth. If the beams are not aligned with our line of sight, the neutron star will not be observed as a pulsar.
Pulsars are located every where around the universe keep in mind pulsars are neutron stars so that means they were formed by large stars that have aged and died out
The connection between pulsars and neutron stars is explained by the generally accepted model that pulsars are rapidly rotating neutron stars that emit beams of radiation from their magnetic poles, causing periodic signals to be observed when the beams cross our line of sight. This emission of radiation is what gives rise to the pulsed nature of pulsar signals.
All young neutron stars in reality are "pulsars". However, for a neutron star to be termed a pulsar, it's magnetic axis has to point towards Earth. (So we can see the pulse, even though all young neutron stars have a pulse, they cannot be observed from Earth.)
All "pulsars" are neutron stars - it's just "we" term pulsars as neutron stars who's orientation towards us shows the beam of electromagnetic radiation. Other neutron stars who's orientation, do not point towards us are not called pulsars, although they exhibit the same characteristics.
