NEUTRON STARS

CHARACTERISTICS

• Very dense and spin very fast
• They are the size of a city
• Don't glow
• Formed from burnt out stars

PULSARS

• Neutron stars emit radio waves
• They pulse on and off
• When the pulse is on the earth receives radio waves
• The escaping radio waves sweep around like the light beam from a lighthouse

COLLIDING NEUTRON STARS

• Pairs of neutron stars can create violent events if they collided.
• At 15.3 seconds into the simulated collision, a black hole has already formed with the mass of 2.9 suns
• At. 26.5 milliseconds, a jet like magnetic field emerges at the poles of the spinning black hole.
• Colliding neutron stars are predicted to produce gravitational waves.

HOW DO WE DETECT THEM

• They don't give off light so it's hard to see them
• Astronomers can find neutron stars by observing the gravitational effects on objects near by
• They can also find them because they emit x rays, satellite can observe the x rays in the sky

FUN FACTS

• It's material would have a mass over 5.5 times ten to the twelfth kilograms, about nine hundred times the mass of the great pyramid of Giza
• They rotate severs times every second, some can get to several hundreds of revolution set seconds
• They can warp light
• They make gravity crazy
• They are not made of neutrons
