A White Dwarf star starts as a small to intermediate size star, like our Sun is currently. That eventually becomes a red giant star. Eventually that blows off everything but the hot very dense core of "electron degenerate matter". What is left is a hot ball of mainly carbon and oxygen that will eventually cool and dim and turn into a black dwarf star.
A white dwarf has a second chance of life and death in a close binary star system, where the white dwarf draws mass from the companion star. Once the mass of the white dwarf reaches the Chandrasekhar limit of approximately 1.38 solar masses or roughly 140% of the mass of our Sun, the core can no longer hold the gravitational pressure and a Type 1a Supernova may occur.
A Red Dwarf star is a " Main Sequence " star, but with very low mass and
luminosity. You need a telescope to see one. However, they make up about
80% of all stars and they have very long lifetimes.
What else can I help you with?
Which is the correct order - white dwarf or red?
The correct order is red giant followed by white dwarf. A red giant is a stage in the life cycle of a star where it has expanded and cooled. After the red giant phase, the star sheds its outer layers and the core collapses to form a white dwarf.
Is a white dwarf smaller than a red dwarf?
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
What stage follows the white dwarf stage of star development red giant prostar neutron black dwarf?
The Neutron stage follows the White Dwarf stage of star development.
What is a low mass star (main sequence)?
A star with a low mass will go through these stages: 1. Protostar nebula 2. Main sequence (as a red dwarf) 3. Red giant 4. Planetary nebula 5. White dwarf (6. Black dwarf is theorized to occur after white dwarf)
What star is known as the faint white star?
The faint white star you may be referring to is Proxima Centauri, which is the closest known star to the Sun located in the Alpha Centauri star system. It is a red dwarf star, emitting mostly infrared and some visible light, giving it a faint white appearance.
Why would a white dwarf become a red dwarf?
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
Which is the correct order - white dwarf or red?
The correct order is red giant followed by white dwarf. A red giant is a stage in the life cycle of a star where it has expanded and cooled. After the red giant phase, the star sheds its outer layers and the core collapses to form a white dwarf.
Star of life?
Nebule > Star > Red Giant > Red Dwarf > White Dwarf > Supernova > Neutron Star > Black Hole.
How a star becames a white dwarf?
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
Is a white dwarf smaller than a red dwarf?
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
What are the two giant and dwarf star?
Red Giants & Blue Giants & White Dwarf star
Steps in the life of a star?
the steps in the life of a star is the yellow dwarf,red giant,white dwarf & the black dwarf.
Is the star proxima centauri a white star?
No. It's a red dwarf star.
What does a life cycle of a star look like?
Nebule > Star > Red Giant > Red Dwarf > White Dwarf > Supernova > Neutron Star > Black Hole.
Is a white dwarf older the a red dwarf?
Not necessarily. A white dwarf is simply the remains of a low to medium mass star that has died. A red dwarf is a low mass star. Since red dwarfs last longer than medium mass stars, one could easily be older than a white dwarf.
What The outer atmosphere of a star?
white dwarf or a red giant
What stage follows the white dwarf stage of star development red giant prostar neutron black dwarf?
The Neutron stage follows the White Dwarf stage of star development.
