A white dwarf star starts out like a our sun and turns into a white dwarf at the end of the stars life cycle. They have used up all their nuclear energy. At the end of this nuclear burning stage the star expels most to all of its outer materials. This creates what is known as a planetary nebula. The hot core is the only part of the star that remains. Temperatures of the core can and will exceed 100,000 Celsius becoming a very hot white. From this point the star starts to cool down, but that takes a billion years or more.

What is the average life span of a supernova?
the nebula stage in a stars life cycle lasts for 25,000 years before turning into a white dwarf and then into a black dwarf.
Explain the role of nuclear fusion in the life cycle of a star?
It's the energy source for all stars (until their fuel is used up - white dwarf stage).
Which of the following will be the final stage in the sun and life cycle?
Most likely it will become a white dwarf.
What is the next stage in the life of a lower-mass main-sequence star?
white dwarf. unless you count black dwarf of which none have been observed, only theorized.
What is a low- meduim- mass star the becomes the end of its life?
White dwarf. High mass stars become neutron stars or black holes.
Are white dwarf stars always white?
No in the life cycle of a star, a white dwarf can cool and become a black dwarf
What is the name for the portion of a stars life cycle when it is using hydrogen for fuel?
white dwarf
Does a star turn into a white dwarf at the end of its life cycle?
Stars with a low to medium mass will become white dwarfs. Massive stars will become neutron stars or black holes.
What is the average life span of a supernova?
the nebula stage in a stars life cycle lasts for 25,000 years before turning into a white dwarf and then into a black dwarf.
Whats the life cycle of the stars?
A star's life cycle starts from a nebula. For giant stars, the star turns into a huge star to a super red giant to a supernova to a black hole. A sun-like star turns to a red giant, then a planetary nebula, a white dwarf, and then a black dwarf.
What is the final stage in the suns cycle life?
White Dwarf then Black Dwarf=Dead Star
Explain the role of nuclear fusion in the life cycle of a star?
It's the energy source for all stars (until their fuel is used up - white dwarf stage).
What are the stages of the sun's life cycle?
protostar, main sequence, giant, nebula, white dwarf & black dwarf.
What are the steps in the life cycle of a small or medium sized star?
The life cycle of all stars is pretty similar from birth to late in their life - that's when the rest of their life cycle can vary dramatically. Small and medium-sized stars tend to be the longest-lived stars (our Sun is a typical example), and they end their life by expanding, cooling, and then blowing off their outer shell while their nucleus collapses to a "White Dwarf".
Which best describe the final in our sun's life cycle?
It will collapse and become a white dwarf
What does a sunlike star become in the final state of it's life cycle?
the answer is white dwarf
What describes the final phase in our sun's life cycle?
It will collapse and become a white dwarf.
