What does the HR diagram show?
It shows the relationship between the mass and color of stars.
The HR diagram illustrates the color of stars based on their size.
It shows the relationship between the brightness/luminosity and temperature of stars.
It shows the relationship distance of stars from Earth and their mass.
Where are the main sequence stars on the HR diagram?
They are found in a circular pattern in the center.
They are found along the diagonal band from the upper left to the lower right.
They are located in the upper right and left corners.
They are scattered randomly.
When the sun or any other similar stars die, they become what?
Red giant
Neutron star
White dwarf
Black hole
These occur in binary star systems, where one of the stars is a white dwarf. The white dwarf pulls material from its companion star. Once it gathers too much material, it becomes unstable and explodes.
Type II supernova
Type I supernova
These happen when a white dwarf reaches a critical mass from pulling in too much matter and explodes.
Type II supernova
Type Ia supernova
These occur when a star at least 8 times the mass of the Sun runs out of fuel. Without fuel, the core collapses under gravity, leading to an explosion.
Type II supernova
Type I supernova
These have a "plateau" in their light curve (brightness stays steady for a while after the explosion).
Type IIP supernova
Type IIL supernova
Type IIb supernova
The brightness drops off in a straight line after the explosion.
Type IIP supernova
Type IIL supernova
Type IIb supernova
These start like Type II but lose most of their hydrogen, so they later resemble Type I supernovae.
Type IIP supernova
Type IIL supernova
Type IIb supernova
