Neutron Stars and Pulsars
Transcript of Neutron Stars and Pulsars
cloud turn into a star? Important sub-detail Neutron stars are
only sort of stars. Well, if neutron stars give off almost no light, then why can we see the one in the photo of that supernova? There are few differences between a Neutron star
and a black hole. Well, what used to be the central region of the star collapses with great intensity. What Happens Next? And? The power of the implosion is so powerful that protons and electrons fuse to become neutrons. Thus creating a sphere mainly made up of neutrons. Now, neutron sounds like "neutral" (and in terms of physics, neutrons indeed are neutral). So neutron stars must be calm environments, right? I would think so. We would both be wrong! You can practically see the magnetic field and gravitational pull! So what is it like on the surface of a neutron star?
How would one affect its surroundings? The environment Well, for one thing, the average gravitational pull of a neutron star is 2022 times that of Earth. Just for the sake of argument, lets say you weigh 100 pounds on Earth. On the average neutron star, you would weigh 202,200 POUNDS!! That's over 100 tons! What does that mean? *Squish* :)
Well, like the presenter said, neutron stars give off
some light, just not much. Lets go back to the supernova... Black holes are basically the same
as a neutron star, but for a black hole,
(as also with the neutron star) there is a powerful implosion, causing it to reach infinite density. Well, neutron stars dont have infinite density. Their densities are usually around 10 g/cm. 14 3 Also, it spins faster than the speed of light, which exponentially increases its mass. Therefore, its gravity is inescapable. Also, Neutron stars don't give off much light--barely any at all, relative to main sequence stars. Woah... that's a lot! Does everything weigh more on a neutron star? Yes! One teaspoon full of neutron star dirt would
weigh 1,000,000,000 tons! How about we move away from this "e"?
:) Alright, so if gravity is stronger, and you weigh more, does that mean you would fall faster? Oh yeah. HECK yeah. If you jumped off of an object that was 4 feet high on a neutron star, you would be going 600mph when you hit the ground! Really? That's amazing! And hard to imagine! Yeah. It sure is! Alright, what about pulsars? Surprised baby Is surprised Pretty OMG Pulsars are just neutron stars that are spinning at an average 1800 times per minute. The Earth spins once every 24 hours. They send off extremely powerful (and dangerous) pulses of energy. Wow, cool! Where did you get all this info, by the way? That's a good question. I'll tell you:
