What are the stages of stars?
The formation and life cycle of stars
- A nebula. A star forms from massive clouds of dust and gas in space, also known as a nebula.
- Protostar. As the mass falls together it gets hot.
- Main sequence star.
- Red giant star.
- White dwarf.
- Supernova.
- Neutron star or black hole.
What are the first 3 stages of a star?
7 Main Stages of a Star
- A Giant Gas Cloud. A star begins life as a large cloud of gas.
- A Protostar Is a Baby Star.
- The T-Tauri Phase.
- Main Sequence Stars.
- Expansion into Red Giant.
- Fusion of Heavier Elements.
- Supernovae and Planetary Nebulae.
What is the first stage of a stars life?
Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity. This image shows the Orion Nebula or M42 . Stage 2 – A region of condensing matter will begin to heat up and start to glow forming Protostars.
What are stages of life cycle?
The major stages of the human lifecycle include pregnancy, infancy, the toddler years, childhood, puberty, older adolescence, adulthood, middle age, and the senior years. Proper nutrition and exercise ensure health and wellness at each stage of the human lifecycle.
What are the end stages 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.
What are the end stages of stars?
Three and stages of stars are white dwarf, neutron star and a black hole.
What is the second stage of a star called?
The main-sequence star is the second stage of a star. This is the stage where a star will remain most of its life.
What are the stages of the life cycle of stars?
Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant. 1. Giant Gas Cloud
What is a main-sequence star?
The main-sequence star is the second stage of a star. This is the stage where a star will remain most of its life. The sun if an example of a main-sequence star. Over millions of years the stars size slowly begins to get smaller because of the heat and energy it is losing.
What happens when a star becomes a white dwarf?
A star like our Sun will become a white dwarf when it has exhausted its nuclear fuel. Near the end of its nuclear burning stage, such a star expels most of its outer material (creating a planetary nebula) until only the hot (T > 100,000 K) core remains, which then settles down to become a young white dwarf.
