What else can I help you with?
What begins the death of a star?
Usually the fact that the star runs out of fuel.
What is a star's main source of fuel?
A star's main source of fuel is nuclear fusion, specifically the fusion of hydrogen atoms into helium in its core. This process releases vast amounts of energy in the form of light and heat, which sustains the star's luminosity and temperature.
When a main sequence star runs out of hydrogen to fuel the core of which type of star begins to form?
red giant
What element does a star run out of that causes them to die?
A star dies when it runs out of fuel to sustain nuclear fusion in its core. This fuel is mainly hydrogen, which gets converted into helium through nuclear fusion. Once the star runs out of hydrogen, it will expand and eventually collapse, leading to its death in a supernova explosion.
What is star fuel?
hydrogen
What does it mean when a star goes off the main sequence?
When a star "goes off the main-sequence" it generally means the star has run out of hydrogen fuel and is beginning the post-main-sequence or its end of life phase. The main sequence of a star is the time where it is no longer just a proto-star but is burning hydrogen as a primary source of fuel.
How is the red-giant formed?
A red giant forms when a star runs out of hydrogen fuel at its core and starts fusing hydrogen in a shell around the core the core. This causes the star to expand and cool.
Why does the amount of hydrogen in a star decrease over time?
The amount of hydrogen in a star decreases over time because the star fuses hydrogen into helium in its core through the process of nuclear fusion. This conversion of hydrogen into helium releases energy that powers the star and results in a gradual depletion of its hydrogen fuel source.
What happens when a star burns all of its hydrogen?
When a star burns up all of its hydrogen,it becomes red in color.As hydrogen is the fuel for star and it will burst after it.
What is the name of the portion of a stars life were it uses hydrogen as fuel?
A star that uses hydrogen as fuel is a main sequencestar.
What triggers a super nova?
When its original source of fuel has run out for instance our sun runs on hydrogen, after the depletion of the original fuel is gone the suns core condenses creating helium were the star expands to great measures were it gets to a size were its limited supply of helium runs out either collapsing into a black hole or a dwarf star
Name of fuel that make the star glow?
Hydrogen
