Low Mass Stars (1)
Low mass Main Sequence Stars spend this amount of time fusing hydrogen to helium in their cores.
What is billions of year?
A former Protostar becomes this.
What is a Main Sequence Star?
Star formation occurs here.
What is a Nebula (Stellar)
A Protostar become this when it does not have sufficient mass.
What is a Brown Dwarf?
The name for when objects in space are moving way from us. Its a type of wavelength.
What is a Red Shift?
The cooling core of a former Red Giant.
What is a White Dwarf.
This occurs to the outer layers of a star whose core begins to shrink due to the depletion of Hydrogen that is then converted into Helium,
What is its outer layers expand?
The stellar evolution from a Protostar to a Main Sequence Star may last this long.
What is 100,000 and 10 million years depending on the size of the star being formed?
An object whose surface gravity is so great that even electromagnetic waves cannot escape from it
What is a black hole?
This is emitted when a Protostar has sufficient mass.
What is light?
It is approximately 13.7 billion years old. And it is not your mom.
What is the age of the universe?
True or False? Planetary Nebulas are areas in space where planets are formed.
False. Planetary Nebulas have nothing to do with Planets.
When hydrogen fusion can no longer take place inside the star’s core these two life altering events occur
What is increase in internal gravity and its core collapses?
What percentage of this life cycles do most Main Sequence Star remain in.
What is 90% of their life cycle?
This is a large interstellar cloud of gas and dust that is composed mainly of hydrogen and helium.
What is a Nebula?
During the process of nuclear this is converted into this.
What is Hydrogen into Helium?
This states that the universe began in an instant. It start off with this enormous explosion.
What is the Big Bang theory?
The layers of Red Giant are ejected into to space in the form of these.
What is ionized gas that glows bright.
Once the outward expansion of a star's out layers takes place it becomes this.
What is a Red Giant?
These three things happens to a star when it runs out of hydrogen.
What is its fusion reactions shuts down and the star begins to shrink and cool?
A very young star before nuclear fusion begins.
What is a Protostar?
When two or more atoms of hydrogen join together.
What is the formation of Helium?
The type of wavelength that occurs when objects are moving towards us.
The glowing gas and debris from a former Red Giant are called this.
What is a Planetary Nebula?
Eventually a Red Giant fuses all of its core Helium into this.
What is Carbon?
A Star’s Life Cycle depends on.
What is its mass?
The process that result in a Protostar.
What is Accretion?
The temperature of the core of a former Protostar,
What is 10 million degrees Celsius?
This is thought to be leftover radiation from when the universe began. It fills all of space.
What is Cosmic Background Radiation?
The matter inside of a White Dwarf Star is this many times more than water.
What is a million times denser than water?
