The Life of a Neutron Star
Birth
Heat and pressure
Once a century
Star collapses
.
Explodes
Nuetrons collapse
Into supernova
Leaves dense ball of matter
Neutron star
Innards cover space with heavy elements
Under own gravitational pressure
Can't produce enough energy
Star's hydrogen fuses into heavier elements
Nitrogen
Iron
Carbon
Helium
Neutron Star
.
Insides
Protons and electrons
Fuse into neutrons
Forms friction-less liquid
Super-fluid
Dense
One of the densest objects in the universe
Compact
Crust
As dense as a fully-loaded container ship the size compacted into a hair
Super fluids form deep
Nuclear pasta
.
Precursors spin
Collapse and compress
Compress to about 25 KMS across
Angular momentum preserved
Neutron spins faster than parent
Record time is 700 spins per second
Beams radiate from magnetic poles
Note aligned with rotational axis
Beams spins
Pulsars
Strongest Magnetic field know
Forms vortexes
Binary Systems
.
Neutron Star co-orbits other star
Neutron star feeds of lighter star
Collapses into a black hole
Neutron Binaries
Circle each other
Merger
Causing gravity waves sent through space
Like ripples from stone into lake
.
Small percentage
.
Theory of General Relativity
Einstein
Predicted this phenomenon 100 years ago
LIGO and VIRGO
2017
observed neutron star collision
telescopes picked up burst of gamma rays
telescopes saw a flash of light
Data helps discover the speed of gravity
helped bolster astrophysic theories
provide evidence- origin of heavy elements
