|
Nebula |
Stellar Factories that create stars; the remnant of dead stars |
|
|
Protostar |
Created from nebula; extremely unstable "baby" stars which is the first stage of a star |
|
|
Main Sequence |
longest stage of a star; stable stars where they fuse hydrogen into helium |
|
|
What affects the color and lifespan of a star? |
Mass and Size |
|
|
Low-Mass Stars |
Stars that have a red to yellow-white color with a long lifespan; They end their lives with a planetary nebula and a white dwarf (then a black dwarf) |
|
|
High-Mass Stars |
Stars that have a white to blue color with a short lifespan that will end their lives with a supernova and then a black hole, neutron star, or a nebula |
|
|
Things that happen after main sequence stars get old |
They will run out of hydrogen and then fuse helium together into heavier elements, which will make it expand |
|
|
What will happen to Earth after the sun becomes a red giant? |
It will be obliterated or boiled to death (Yay! We have such a positive future) |
|
|
Planetary Nebula |
The remnant of most of the low mass stars besides the core; it is formed one the star reaches heavier elements and just collapses by its inability to fuse that heavier elements |
|
|
White Dwarf |
The remnant of the core of low mass stars; it is extremely dense and will continue to burn a small amount of fuel for a few more hundred billion years before it runs out and dies |
|
|
Black Dwarfs |
A white dwarf that after a few hundred billion years runs out of fuel and dies into a black ball of sadness; it is theoretical thing
|
|
|
Supernovas with stars |
Explosions that happen after high mass stars are unable to fight gravity and contract inwards, and then explodes |
|
|
Neutron Stars |
Unusual stars that are 99.99% made of neutrons that constantly spins and emit pulsars |
|
|
Black Hole |
Mysterious holes through space time that sucks in anything beyond the event horizon |
|
|
How can we detect black holes? |
Using x-ray telescopes |
|
|
How far away is the sun? |
93,000,000 miles |
|
|
Plasma |
state of matter that is created by being exposed to extreme temperatures |
|
|
Core |
Center of the sun where nuclear reactions and fusion occur |
|
|
Radiation Zone |
Next to the core; where movement of energy occurs |
|
|
Interface Layer |
Next to the radiation zone and convection zone; generates the magnetic field |
|
|
Convection zone |
Next to the interface and the sun's atmosphere; Atoms convect here and it is relativity cold here |
|
|
What is the sun's atmosphere made up of? |
Photosphere, Chromoshere, and Corona |
|
|
Photosphere |
Visible surface of the sun; means sphere of light |
|
|
Chromosphere |
Thin-reddish layer above the photosphere |
|
|
Corona |
Final layer of the sun, halo surrounding the sun, only seen in a solar eclipse |
|
|
Solar Wind |
Made of particles that escape the gravity of the sun. They have a magnetic charge and fuse together
|
|
|
Solar Flares |
Sudden, violent explosions that occur near the sunspots |
|
|
Sunspots |
Cool, dark areas on the sun |
|
|
Order of the layers of the sun, center and out |
Core, radiation zone, interface layer, convection zone, photosphere, chromosphere, corona |
|
|
Colors in the H-R Diagram |
Blue, Blue-White, White, Yellow-White, Yellow, Red-Orange, Red |
|
|
Absolute Magnitude |
the amount of light generate from the surface of stars |
|
|
What is stellar temperature measured in? |
Kelvin |
