Are all pulsars neutron stars?
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.)
What are the byproducts of Supernovae?
All the elements of the periodic table apart from hydrogen and helium are synthesised in the explosion of a supernova.
What is the relationship between the words supergiant supernova neutron star and black hole?
They are all astronomical terms for stars or star related.
Do all words contain a prefix?
no
What countries contain metamorphic rocks?
All countries!
Are pulsars found in supernova remnants.?
Yes. All pulsars and neutron stars are the remnants of a supernova explosion.
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.
Why are pulsars hot?
Pulsars and neutron stars are hot because of all the residual heat left over in the core of the original star.
Instellar gas is composed mainly of?
Mainly hydrogen, with small of helium, ammonia, methane and other trace gasses. Also, a lot of dust.Some of the hydrogen may be primordial, remnants from the Big Bang that we believe created the universe. But all of the heavier elements (and some of the hydrogen) are the remnants of old supernova explosions, the ejecta from the destruction of the original stars.
Do all objects give off pulsars?
Pulsars are highly magnetized, rotating Neutron_starthat emit a beam of Electromagnetic_radiation. The radiation can only be observed when the beam of emission is pointing towards the Earth. This is called the lighthouse effect and gives rise to the pulsed nature that gives pulsars their name
What kind of electromagnetic radiation do pulsars emit?
All electromagnetic wave lengths (light)
Why do all stars end in a supernova?
Oops! Not all stars end up as a supernova. To become a Type 2 supernova, the star has to be between 8 and 50 times larger than the Sun.
What happens if all the stars supernova?
we all die
Are all pulsars neutron stars?
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.)
Is the sun a planetary nebula or supernova?
Oh, sure. The Sun is a Supernova. That's why we're all sitting here burning to death.
Are all the stars you see at night really stars?
Besides the stars that you can see, there are five visible planets; Mercury, Venus, Mars, Jupiter, and Saturn. Venus and Jupiter are generally brighter than any stars. Additionally, there are about 500 visible nebulas, which are tiny cloud-like structures. Some are gas clouds, some are galaxies, and some are supernova remnants, but these are all around stars, contain stars, or used to be stars. With the naked eye, they are pretty much star-like, but with a moderately powerful telescope you will be able to see the details of them.
What do you mean when you say every pulsar is a neutron star but not every neutron star is a pulsar?
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.
