A young neutron star. Really - that is what a neutron star is.
If the neutron star's magnetic field is pointed towards Earth, then it is referred to as a pulsar - because of it's rapid pulsations [See related question] but it is still a neutron star.
A neutron star.
You maybe thinking of a Pulsar, but they are basically the same.

Yes, a neutron star with fast enough angular velocity produces jets of radiation from their poles and are known as pulsars.
Yes. A pulsar is a rapidly spinning neutron star.

Observations show that neutron stars spin very rapidly.
The fastest spinning neutron star that we've found so far is XTE J1739-285, which spins 1122 times every second. It was found by NASA's Rossi X-Ray Timing Explorer (RXTE) satellite. The most rapidly spinning pulsar, however, remains PSR J1748 2446ad, which spins 716 times a second. This pulsar was found by a team at Montreal's McGill University.
Yes. A pulsar is a rapidly spinning neutron star.
It is still called a neutron star. Depending on how we observe it, it may also be called a pulsar.

A pulsar is a rapidly-spinning neutron star, the remains of a supernova explosion.
A pulsar is a rapidly spinning neutron star that releases regular pulses of electromagnetic radiation from its magnetic field
"Small but very dense" sounds like the description of a neutron star or "collapsed matter star". Theoretically, a black hole (the only thing more dense) has no physical size at all. So, "neutron star". If the neutron star is spinning rapidly, they are called "pulsars" for the radio-wave pulses that they generate.
Studying star and star types can be fun, but it can be challenging to remember each type. A Neuron star is a dense, rapidly spinning star.
If it also emits pulses in each rotation, it is called a pulsar.
A radio pulsar or a rotation-powered pulsar. A link is provided for more information.
A pulsar
supernova remnant
A pulsar is a type of neutron star, a collapsed core of an extremely massive star that exploded in a supernova. Whereas white dwarfs have incredibly high densities by earthly standards, neutron stars are even denser, cramming roughly 1.3 solar masses into a city-sized sphere.
