Is a white dwarf considered a main sequence star?
No, a white dwarf is not considered a main sequence star. A main sequence star is a star that is still fusing hydrogen in its core. A white dwarf is the remnant of a low to medium mass star in which fusion has stopped.
Why is a white dwarf considered a dead star?
A white dwarf is not considered a "dead star." It is considered a dying star, but not dead yet. A white dwarf is at its smallest state and could become a supernova when its center runs out of fuel to burn.
Can Sirius b burn hydrogen as fuel?
No. Sirius B is a white dwarf. It is the remnant of a star that used up its supply of hydrogen.
What is an explosion seen when a white dwarf captures H from a companion star?
When a white dwarf star accretes hydrogen from a companion star, it can trigger a runaway nuclear fusion reaction that causes a sudden and bright increase in brightness called a nova. This explosion is not as powerful as a supernova, and the white dwarf usually survives to potentially experience multiple nova events.
What will be the sun be white dwarf or a main-sequence star?
Right now the sun is a main sequence star. When it uses up the hydrogen in its core it will become a red giant then shed its outer layers to become a white dwarf.
A star that is a has exhausted its supply of hydrogen?
A star that is a white dwarf has exhausted its supply of hydrogen.
What gas is being used as a fuel source for the white dwarf?
The gas being used as a fuel source for white dwarfs is primarily hydrogen. During nuclear fusion reactions in the core of a white dwarf, hydrogen atoms are fused together to form helium, releasing energy in the process.
Is a white dwarf considered a main sequence star?
No, a white dwarf is not considered a main sequence star. A main sequence star is a star that is still fusing hydrogen in its core. A white dwarf is the remnant of a low to medium mass star in which fusion has stopped.
What kind of star forms when a white dwarf uses up all its energy?
A white dwarf is the remains of a dead star, not the birth of a new one.
Why would white dwarf stars have less amount hydrogen?
A white dwarf is the remnant of a star that has fused all the hydrogen and helium in its core, leaving mostly carbon and oxygen nuclei.
What type of star used up all of its hydrogen and its leftover center of an older star?
this is called a white dwarf
Why is a white dwarf considered a dead star?
A white dwarf is not considered a "dead star." It is considered a dying star, but not dead yet. A white dwarf is at its smallest state and could become a supernova when its center runs out of fuel to burn.
When a white dwarf star no longer emits energy what does it become?
When a white dwarf star no longer emits energy, it becomes a black dwarf. Black dwarfs are theoretical end points of stellar evolution where all nuclear reactions have ceased, and the star has cooled down to the background temperature of the universe.
What is the relationship of giant white dwarf and black dwarf?
A white dwarf star is a star that has burned off all of its helium and hydrogen fuel, but which is still hot. After it cools off (which would theoretically take hundreds of billions of years), it would become a black dwarf.
Is a dwarf star and a white dwarf the same thing?
No. A dwarf star is a small star. A white dwarf is just one particular type of dwarf star, but there are other types.
When a white dwarf star no longer emits energy it maybe come?
A black dwarf [See related question]
Is the white dwarf the biggest star?
No a white dwarf is a small compact star.
