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 once the mass is large enough and nuclear fusion occurs.
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.
During this pre-birth stage, the core of the collapsing cloud is hot and dense but has not yet begun nuclear fusion.
What is a Protostar?
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?
A low-mass star, like the Sun, will shed its outer layers, creating this beautiful, expanding shell of gas around its core.
What is a Planetary Nebula?
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.
An object whose surface gravity is so great that even electromagnetic waves cannot escape from it
What is a black hole?
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.
In this final pre-collapse stage, the star's core has multiple shells fusing elements up to iron, which represents a critical boundary.
What is Multiple Shell Burning (or Fusion of Heavier Elements)?
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?
This catastrophic, powerful explosion occurs when the iron core collapses, leading to a shockwave that blasts the star's outer layers into space.
What is a Supernova (or Core-Collapse Supernova)?
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?
What is a Supernova (or Core-Collapse Supernova)?
What is a Neutron Star (or Black Hole)?
