How does the sun change over time?
Temperature, mass, Brightness
What happens inside the sun
Nuclear Fusion
What is the equation for nuclear fusion
H + he
What stage is the sun in
Main sequence
What will happen to the sun when It runs out of C - O
it will undergo a planetary nebula and will become a white dwarf
What will happen when the sun becomes a giant
it will start fusing he > c
What are 2 different scientific ways of looking at the sun
Apparent and absolute magnitude
What is apparent magnitude
Apparent magnitude is what a star looks like (how bright it looks) or what you see with your eyes
What is absolute magnitude
Absolute magnitude is when you put all the stars at the same difference and see how they look
what diagram talks about types of stars
H-R Diagram
What are stars like in the main sequence
baby stars, Sun starts of as main sequence
What are stars like in the supergiant/ Giant stage
super old stars
What is solar radius
How big a star is compared to the sun
What stage do all stars begin in
Main sequence
What Determines the final stage of a star
Mass
What stage are stars born in
Stellar Nebula
When do stars form
When nuclear fusion occurs
What’s a black hole
Sucks in stars and doesn’t let light out
What stage is the end of a stars life
Supernova
How are you able to see what elements are in stars
Stars spectra
What do dark lines on the spectrum show
gas absorbed light absorbed by gases in a star
What is redshift?
A star / galaxy that’s moving away from us
Whats the difference between longer wavelengths and lighter wavelengths
Light waves are stretched ; longer wavelengths are red and at the end of the spectrum
How can you tell if something is redshift
When the spectralines move to the right side towards the red side
