Neutron stars: good short article

In summary, Gordon Baym writes that neutron stars are strange and fascinating objects and that one reason it's good is that it is written for the Wiley Encyclopedia of Physics.

Neutron Stars
Gordon Baym, Frederick K. Lamb
Comments: Encyclopedia of Physics 3rd ed., R.G. Lerner and G.L. Trigg, eds., Wiley-VCH, Berlin

Abstract: "This short encyclopedia article, reviewing current information on neutron stars, is intended for a broad scientific audience."

It is only 3 pages and jams a lot of interesting facts about the topic into small space.

It had stuff I didnt know about the crust and about the core. the whole star isn't made just of neutrons. you might find it worth checking out

I always enjoy discovering new things about monsters of the kind of neutron stars. In this occasion, the thing that is new to me is the concept of "neutron drip point", that is, the point where the density of neutrons is so high that not all can be accommodated in the nuclei and some become free

Gotta love the articles like that, direct and to the point

For a nice entry-level lecture on white dwarves, neutron stars and black holes by Walter Lewin, click here and scroll down a little way.

IIR, he says that a marsmallow dropped onto the surface of a neutron star will arrive at a substantial fraction of the speed of light and will release as much energy as the Hiroshima A-bomb.

I always suspected marshmallows were not as innocuous as they appear. Neutron stars are indeed bizarre denizens. Physicists would love to know goes on in the core. There is some speculation the core is actually a quark star.

I imagine that a pickled squirrel head (much more massive than a marshmallow, you must agree) would release energies greater than the total of the military arsenals of many countries. I am going to report you to the U.S. head of Homeland Security, since it is by now obvious that you are a serious threat to the continued existence of the Earth. It is obvious now why you have been hoarding pickled squirrel heads, instead of sending them to me for family get-togethers, etc. The only remaining component you need now to complete your doomsday machine is a neutron star!

1. What is a neutron star?

A neutron star is a highly dense celestial object that is formed from the core of a massive star after a supernova explosion. It is composed almost entirely of neutrons and has an incredibly strong gravitational pull.

2. How are neutron stars formed?

Neutron stars are formed when a massive star runs out of nuclear fuel and collapses under its own weight. The core of the star collapses and the protons and electrons combine to form neutrons, resulting in a neutron star.

3. What makes neutron stars unique?

Neutron stars are unique because of their incredibly high density and strong gravitational pull. They are also the smallest and most compact stars in the universe, with a diameter of only about 10-15 kilometers.

4. Can we observe neutron stars from Earth?

Yes, we can observe neutron stars from Earth using telescopes and other instruments. However, they are not visible to the naked eye and can be difficult to detect due to their small size and distance from Earth.

5. How do neutron stars affect their surroundings?

Neutron stars can have a significant impact on their surroundings. Their strong gravitational pull can distort the space-time around them, and they can also emit powerful radiation and magnetic fields that can influence nearby objects such as planets and other stars.
