Spectroscopically Speaking
This Harvard astronomer developed the classification system which is used for stars.
Who was Annie Jump Cannon
The stars that are between group G stars and group M stars
What are Group K stars
This is the birth place of all stars
What is a Nebula?
This equation is used to relate a Star's peak wavelength with it's temperature
What is Wein's Law?
This is a graph of a star's luminosity vs it's temperature
What is a Hertzsprung Russell diagram?
This is the stage of formation just prior to the onset of fusion
What is a protostar?
Eventually our sun will fuse helium into this element
Carbon
The wavelengths of light between approximately 400 and 700 nm
What is the visible spectrum?
These are stars with masses lower than around eight times our sun's mass
What are low mass stars?
This star is characterized by the fusion of Hydrogen into Helium
What is a Main Sequence Star?
The collapse of a star's core generates vast numbers of these subatomic particles
What are Neutrinos?
The detection of this feature helps astronomers determine a star's make-up.
What is an emission (or absorption) spectrum?
This stage of a star's life is characterized by the fusion of Helium in the core and the burning of Hydrogen in the shell
What is a red giant?
The creation of heavy elements during a supernova explosion
What is Nucleosynthesis?
These two factors contribute to the apparent brightness of a star in our night sky
What are (absolute) luminosity and distance?
an astronomical feature formed by an expanding shell of gas around an aging star
what is a planetary nebula?
A star becomes a ticking time-bomb when silicone starts fusing into this element
What is Iron?
This is the surface around a black hole, where the escape Velocity is the speed of light
What is the event horizon?
