Neutron Stars

By: Reina and Dane

What Is A Neutron Star?

• A Star made entirely out of neutrons• Remains of stars that had btw 1.4

and 9 times the mass of out sun

What Do They Do?

• After a star goes nova:– Remaining core collapses–Outer layers blasted into space Result

of Nebula– Gravity condenses the core to about 25

km in diameter in a few seconds***It’s so dense, a pinhead’s worth of

material can weigh as much as a supertanker!!!!

Why is it able to shrink?

• Electro-Magnetic Force (EM) :- Keeps electrons out of the atom’s nucleus

• Star’s mass and gravity is able to overcome EM force

• In the brief seconds EM force is broken, then electrons and protons are combined.

What’s Inside?

• Simple main three layers:- Solid core- “Liquid” mantel- Thin solid crust

Axis

• TWO Axis:-Magnetic -Rotational

Which brings us to…..

Pulsar

• Same thing as a neutron star with one added feature:-Emits 2 high-energy beams, concentrated along magnetic axis

• Beams made of material stolen from companion star– Particles accelerated to

speeds as 20% the speed of light!!!!

MAIN POINTS• Neutron stars are

mainly made out of neutrons

• It has three main layers

• There are two axis• Pulsar emits two

high-energy beams
