What is the life cycle of a one solar mass star?
Once the core starts to fuse to carbon, the star is classified as a red giant. The core will keep on fusing into carbon, but once the helium runs out, the outer layer of the star will drift off as a gaseous shell and change into a Planetary Nebula.
What will a 1 solar mass star become?
Stage 5 – A star of one solar mass remains in main sequence for about 10 billion years, until all of the hydrogen has fused to form helium. The core becomes a White Dwarf the star eventually cools and dims. When it stops shining, the now dead star is called a Black Dwarf.
How long does 1 solar mass star spend in the protostar phase of its life?
Once such a large amount of gas and dust huddle together, they form what we call a protostar. An object is considered a protostar for as long as material is still falling inward. For our Sun, and stars of the same mass, the protostar phase would have ended after approximately 100,000 years.
What are the stages of a low mass star?
Low mass star
- Main Sequence. Low mass stars spend billions of years fusing hydrogen to helium in their cores via the proton-proton chain.
- Red Giant. When hydrogen fusion can no longer happen in the core, gravity begins to collapse the core again.
- Planetary Nebula.
- White Dwarf.
What is the life cycle of a small star?
Small stars, like the Sun, will undergo a relatively peaceful and beautiful death that sees them pass through a planetary nebula phase to become a white dwarf, which eventually cools down over time and stops glowing to become a so-called “black dwarf”.
Which of the following stages in a star’s life is the longest?
Explanation: The Star remains the longest in the stage when it is burning Hydrogen into Helium. For our Sun this is called the main sequence stage which will last for about 4.5 Billion years more , this depends on how fast the star is burning up fuel.
What is the end state for 1 solar mass star?
Our Sun will eventually exhaust its core hydrogen and evolve off the main sequence into a red giant. After the helium flash initiates helium-burning it will move onto the horizontal branch then expand to become an AGB star.
