What are the stages of a low mass star?
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 final stage of a low mass star quizlet?
Explanation: A star that lives 10 billion years is a low-mass star. Its final stage of evolution is a white dwarf. A star is on the horizontal branch of the HR diagram.
What are the three end stages of stars?
Three end stages of stars are:
- White Dwarf.
- Neutrons Star.
- Black Hole.
What is the first stage of a low mass star called?
protostar
Gravity can pull some of the gas and dust in a nebula together. The contracting cloud is then called a protostar. A protostar is the earliest stage of a star’s life. A star is born when the gas and dust from a nebula become so hot that nuclear fusion starts.
What are the stages of a low mass star quizlet?
Terms in this set (11)
- Low Mass Stars. Stars with a mass of less than 4 times that of the sun (2 x 10^30 kg)
- Stage 1: Main Sequence Phase.
- Stage 2: Hydrogen Exhaustion.
- Stage 3: Red Giant.
- Stage 4: Helium Flash.
- Stage 5: Horizontal Branch.
- Stage 6: Asymptotic Giant.
- Stage 7: Core-envelope Separations.
Which of the following sequences correctly describes the stages of life for a low mass star quizlet?
It becomes a white dwarf. Which of the following sequences correctly describes the stages of life for a low-mass star? protostar, main-sequence, red giant, white dwarf.
What is the final stage of a star?
A planetary nebula is the final stage of a Sun-like star. As such, planetary nebulas allow us a glimpse into the future of our own solar system. A star like our Sun will, at the end of its life, transform into a red giant. Stars are sustained by the nuclear fusion that occurs in their core, which creates energy.
What is the dying stage of a star?
When the helium fuel runs out, the core will expand and cool. The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf. This entire process will take a few billion years.
What is the final stage of existence for each type of star?
planetary nebulas
A planetary nebula is the final stage of a Sun-like star. As such, planetary nebulas allow us a glimpse into the future of our own solar system. A star like our Sun will, at the end of its life, transform into a red giant. Stars are sustained by the nuclear fusion that occurs in their core, which creates energy.
What are the life stages of a low mass star quizlet?
Terms in this set (5)
- Star Forming Nebula.
- Nuclear Fusion Begins, Protostar.
- Core Pressure Balances Gravity, Main Sequence Star aka adult.
- Fuel Runs Out, Forces Unbalanced, Red Giant.
- White Dwarf with a planetary nebula (nothing to do with planets)
What is the lowest mass that a star can be quizlet?
The smallest mass possible for a star is about 8% that of the Sun (80 times the mass of the planet Jupiter), otherwise nuclear reactions do not take place.
What is the life cycle of a high mass star?
High-mass stars have lives of 10 million years, versus 10 to 50 billion years or more for low-mass stars. At the end of a high-mass star’s fusion process, iron composes the star’s core. No nuclear fusion of iron is possible out of a high-mass star core, which has the same mass as our entire Sun.
