Our sun
Small- Medium
Image 1
What type of sunspot is this?
Big spot
Where does proton-proton fusion happen?
Core of a star
How does every star start it's life cycle
Nebula
How is a star's temperature and luminosity related?
Direct relationship
What force pushes inward on the sun?
Gravity
Image 3
what type of sunspot is this?
Mixed magnetic fields
How are elements bigger than iron made?
Supernova
What are two things that a large star can become at the end of it's life
Black hole
Neutron Star
What is the relationship between a star's size and how long it will live
Inverse relationship
What force pushes outward in the sun?
Nuclear Fusion (Proton-Proton Fusion)
What causes sunspots
Difference in speeds between the poles and the equater cause mixed magnetic fields
What two elements are apart of nuclear fusion in our sun?
Hydrogen and Helium
Why does a supernova happen?
The fusion in the core is weaker than the gravity and it collapses in on itself
The sun is a mass of....
incandescent gas
How will our sun "die"
White dwarf and planetary nebula
What are 3 different effects of intense solar activities?
Destroy/ Damage satellites
Power grid failures
Communications disruptions
Extreme auroras
Many more!
What does nucleosynthesis mean?
Nucleus building
Main sequence
How much longer before the sun starts to "die"
5-6 billion years
Why does it take so long for a photon to travel through the radiative zone?
Radiative zone is densely packed
How many years does it take for the sun's magnetic lines to reset?
about 11 years
The energy stars get from nuclear fusion with iron is not enough to sustain them
How does a nebula become a star?
Gravity from the nebula causes the nebula to collapse in on itself. often times this is caused by a disturbance
How does E=mc2 relate to how the sun produces energy?
Mass difference between 4 hydrogen and 1 helium is converted at a rate of E=mc2
Energy= E, m= mass, c= speed of light
