Is A pulsar is a white dwarf true or false?
False. A pulsar is not a white dwarf; it is a highly magnetized, rotating neutron star that emits beams of electromagnetic radiation. Pulsars are the remnants of supernova explosions, while white dwarfs are the remnants of low to medium-mass stars that have exhausted their nuclear fuel and shed their outer layers.
Why don't all supernova remnants contain pulsars?
A "pulsar" is a rapidly-rotating neutron star, with a core of collapsed matter. The pulsar rotates because the original star rotated. If\\ WHEN a massive star becomes a supernova, the force of the explosion will crush the core of the star into either a neutron star or a black hole, if the original star was massive enough. The angular momentum (the "spin energy") of the original star doesn't disappear; like a figure skater pulling in her arms to spin faster, the neutron star will spin more rapidly because it has collapsed in size. If the neutron star's axis is pointed somewhere close to Earth, we detect the pulsating x-rays and we call it a "pulsar". So to answer the question, all supernova remnants contain either neutron stars or black holes, but they are pulsars only if they spin rapidly.
What types of stars are thought to be the remnants of supernova explosions?
Supernova explosions are believed to generally result in a black hole, as the core of the star is collapsed into an unimaginably dense point mass. One can't really say that a black hole is any kind of star. Less powerful nova explosions probably result in pulsars or neutron stars.
What element is normally a rement of a supernova?
Elements such as gold, silver, and uranium are typically remnants of a supernova explosion. These heavy elements are formed during the intense energy release of a supernova event.
What is the Vela Supernova?
The Vela Supernova is the remnant of a supernova explosion that occurred in the Vela constellation about 11,000 to 12,300 years ago. It is located about 800 light-years away from Earth and is one of the closest known supernova remnants to us.
Do all supernova remnants contain pulsars?
No. Some supernova remnants contain black holes.
How are pulsars related to supernovas?
Pulsars are formed during a supernova event when a massive star explodes, leaving behind a dense core called a neutron star. As this neutron star rotates rapidly, it emits beams of radiation that we detect as pulses, hence the name "pulsars." So, pulsars are directly related to the remnants of supernova explosions.
How are pulsars and supernovas related?
A supernova will create the pulsar.See related question.
What produces pulsars?
Pulsars are produced from the remnants of massive stars that have undergone supernova explosions. When these stars collapse, they form neutron stars, which are incredibly dense and possess strong magnetic fields. As the star rotates, the misalignment of its magnetic axis with its rotation axis emits beams of radiation, which can be detected as regular pulses of light or radio waves when they sweep past Earth. This phenomenon results in the characteristic pulsing behavior of pulsars.

Why do supernova remnants emit X rays?
because they are filled with hot gas
What element is normally a rement of a supernova?
Elements such as gold, silver, and uranium are typically remnants of a supernova explosion. These heavy elements are formed during the intense energy release of a supernova event.
What are the different kinds of nebula?
Reflection, Hydrogen, Dark, Planetary, Supernova Remnants, Emission.
What is the Vela Supernova?
The Vela Supernova is the remnant of a supernova explosion that occurred in the Vela constellation about 11,000 to 12,300 years ago. It is located about 800 light-years away from Earth and is one of the closest known supernova remnants to us.
What shape is a supernova?
At the initial explosion, they would be spherical as pressure would be equal around the dying star. However as the expanding gases cool and mix, they can take on any shape imaginable. [See Link for pictures]
What are some of the weirdest things in the universe?
Black holes, Quasars, Dark Matter, Rouge Planets, Pulsars, Neutron stars, supernova, Gravity and Human Beings.
