Onions and Ogres
The layer of a star that is visible.
What is the photosphere?
What is a protostar?
Equations that represents the process of fusion.
E=mc^2
Massive explosions caused by large stars
super nova
What is gravity?
What is the core?
Massive cloud of gas with star forming potential
What is a nebula?
The heaviest element a star can fuse.
What is Iron?
Explosions causes by smaller stars
What is a planetary nebula?
The phase that stars spend most of their life.
What is main sequence?
What is convection?
The final state for a star about as massive as our sun.
What is a black dwarf?
The process by which two atoms combine and mass is converted to energy.
What is Nuclear fusion?
Over the course of a stars life what happens to its mass?
it decreases.
What do Black dwarfs, Black holes and neutron stars have in common?
Each is the end stage of a star with different masses.
Radiative zone;Convective Zone; Corona
Stars that have about 10-29 solar masses form these.
What is a neutron star?
this is the most important factor in determining the rate of fusion.
the force of gravity in the core (caused by the mass of the star).
The end result of stars that has 30 solar masses
The Centauri system
Causes sunspots to form in the photosphere.
What are magnetic fields?
Explain the relationship between a white dwarf and a black dwarf.
a black dwarf comes after a white dwarf after the remain energy from fusion has radiated away.
Star 1 is fusing Helium and Hydrogen to produce Lithium
Star 2 is fusing Oxygen and Silicon to produce Iron
Star 3 is fusing 3 Helium atoms and producing carbon
What can you determine from this data about the relative ages of the stars?
Star 2 is the oldest and is closest to death
Star 3 is the middle aged star
Star 1 is the youngest
Causes a black hole to be black.
How is plasma formed
in extremely hot conditions the electrons are pulled off of its electrons through a process called ionization.
