What is the differences of a protostar and a white dwarf?
A protostar is a star that is still forming and has not yet started a sustained fusion reaction. All the heat is the result of gasses being compressed. A white dwarf is the remnant of a dead star that has exhausted its fuel and is much smaller and denser than a protostar.
What is the difference between a brown dwarf and a protostar?
A protostar is a star the is developing as is on the way to starting nuclear fusion. A brown dwarf is a failed star, one that failed to gather enough mass to start fusion.
Which type of star is NOT undergoing nuclear fusion?
A protostar; also a brown dwarf.
What is the life cycle of a yellow star?
Nebula protostar mid sized star red giant nova white dwarf black dwarf:)
What are the seven step in the cycle of a star?
Stars have several cycles in their lifespan. The seven cycles of a star like our sun are Stellar Nebula, Protostar, Main sequence star, Red Giant, Planetary Nebula, White Dwarf, and Black Dwarf.
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 does each star explode into?
The life of a high mass star goes like this: A nebula gets hot and nuclear fusion binds it into a high-mass protostar the protostar ages into high-mass, very hot star that hot star explodes into a supergiant, which proceeds to explode into a supernova the supernova then shrinks into a neutron star or a black hole the life of a low- or medium-mass star goes like this: a nebula gets hot and nuclear fusion binds it into a low-mass protostar the protostar ages into a low- or medium- mass,cool star the star explodes into a red giant, the red giant explodes into a planetary nebula the nebula shrinks into a white dwarf, which then dims into a black dwarf i hope i was able to answer your question.
What are the developments of a star?
1. Nebula 2.Protostar 3.Main-Sequence star 4.Expanding star 5.Red giant 6.Planetary Nebula 7.White dwarf
What are the stages of the stars starting with stellar nebula?
When a nebula slowly collapses, a ball of un-ignited hydrogen called protostar forms. As the protostar shrinks smaller, nuclear fusion starts, and the protostar became a main-sequence star; if the protostar is too small, it would become a brown dwarf and slowly cool down. After burning or millions or billions of years, the main-sequence star would evolve differently based on their sizes. Red dwarfs would become a white dwarf, then slowly cool down. Medium-sized stars (such as our Sun) would expand into a red giant, blow off its outer layers, and leave a core behind; the shell becomes planetary nebula, and the core becomes a white dwarf, the white dwarf would then cool down into a black dwarf. If a star is more than 8 times the mass of the Sun, it would expand into a supergiant, then it explodes as supernova. After the supernova, the outer shell would become a nebula, and the core would evolve into either a neutron star or a black hole.
9 stages of a star?
Stellar nebula: a cloud of gas and dust in space. Protostar: a young star still forming through gravitational collapse. Main-sequence star: stable fusion of hydrogen into helium in the star's core. Red giant: expansion of the star as it runs out of hydrogen fuel. Helium fusion: fusion of helium atoms in the core. Planetary nebula: outer layers of the star expelled into space. White dwarf: the core left behind after the outer layers are ejected. Black dwarf: a cooled and dim white dwarf. Supernova or black hole: the final stage, depending on the mass of the star.
When will NGC 6720 enter the protostar stage?
It will not, at least not on its own. NGC 6720 is not the sort of nebula that produces new stars; it is a planetary nebula formed from the gasses expelled from a dying star. At its center is a remnant called a white dwarf.
When a red giant completes helium fusion and collapses it becomes a . protostar red dwarf white dwarf neutron star black hole?
When a red giant completes helium fusion, it typically sheds its outer layers, resulting in a planetary nebula. The core that remains becomes a white dwarf, which is a dense, hot remnant composed mostly of carbon and oxygen. Over time, the white dwarf will cool and fade. In more massive stars, the process may lead to the formation of neutron stars or black holes, but for a typical red giant, the end product is a white dwarf.
