It's About Mass
A star that is more than 10 solar masses is considered this classification and will follow this life cycle path.
What is a High Mass Star?
This element is generated from Hydrogen in a main sequence star.
What is helium?
The process by which the Sun produces energy.
What is nuclear fusion?
This term is used to describe how elliptical or how circular an object's orbit is.
What is eccentricity?
Term to describe the attraction between 2 objects.
What is gravity.
All star's 1st stage of life occurs in a nebula. This stage is known as...
What is a protostar?
Elements heavier than Iron (Fe) are formed during this stage.
What is Supernova?
This is converted to energy on the core of the Sun.
What is mass?
Kepler's 2nd Law and equal areas in equal time is used to describe this about an object in orbit.
What is velocity?
If the product of this increases between two objects, the gravitational attraction strengthens.
What is mass?
This stage of a star's life is characterized by hydrogen converting into helium.
What is Main Sequence?
The process of forming elements/matter in the core of a star is known as...
What is stellar nucleosynthesis?
This equation is used to describe how mass is converted to energy.
What is E = mC2?
The square of the orbital period is proportional to the cube of the semimajor axis.
What is Kepler's 3rd Law?
As the distance between two objects increases, then the gravitational attraction will...
What is weaken or decrease?
This stage is seen on the HR diagram at the very top and to the right of the main sequence.
What is supergiant or red supergiant?
The red giant and red supergiant form this element from helium.
What is Carbon?
The scale of energy production by nuclear fusion is much greater than that of an electron bonding process called...
What is a chemical reaction?
When a planet is at its closest approach to the Sun, is is said to be at...
What is perihelion?
When Halley's comet approaches Earth, the comet's velocity will..
What is increase?
Iron in the core of a star is a pre-cursor to this stage of a star's life.
What is a Supernova?
This specific type of nuclear fusion chain reaction shows how H becomes and He and converts mass into energy.
What is the Proton-proton chain reaction?
The energy transfer process by which energy travels from the Sun to the Earth.
What is radiation?
The radius of an orbit or ellipse is also called...
What is the semimajor axis?
This position in an object's orbit has the most gravitational attraction and therefore the greatest orbital velocity.
What is perihelion?
