The astronomical names for these objects are: Black hole = black hole. A singularity is a mathematical object. It is a very general term. In General Relativity, once matter crosses into the event horizon, it must move towards the centre of the black hole's mass (we know of nothing to stop it) and everything will find itself crowded into a single point; that is why cosmologists -- the mathematicians of astronomy -- call it a singularity. Neutron star = neutron star. A star so dense that it is made up of neutrons. It is the result of a collapse, where only neutron degeneracy pressure could stop the collapse. A collapsar is the result of a hypernova (the improved supernova, with better taste and more vitamins...): a gamma ray burst plus a freshly created black hole. Degeneracy pressure was insufficient to stop the collapse. A pulsar is a neutron star that has a strong, collimated magnetic field at an angle with the star's axis or rotation, and where the field interacts with the plasma atmosphere in order to produce electromagnetic radiation that is beamed in such a way that it sweeps Earth. A magnetar is another form of neutron star with a very strong magnetic field, where the crystalised iron crust breaks (as the shape of the star's equatorial bulge changes) and gets rearranged, releasing magnetic energy (recombination energy). A dwarf star (called a dwarf star) is also a collapsed star, but one where the collapse was stopped by electron degeneracy pressure (i.e., individual atoms still exist). The result of the collapse of a less massive star.

This Site Might Help You.
RE:
in astronomy another name for black hole, neutron star or white dwarf?

astronomy is a subject.
black holes, neutron stars are objects.
we study objects in a subject.
when we study astronomy, we are taught about what are
black holes & neutron stars. Experimental astronomy
involves collecting evidence about them & their properties.
In theoretical physics and astronomy, you can study then theoretically

Hi. They are all usually the end stage of a star's life cycle.

edit..it's collapsar

Dead star?
Collapsed star?
