Planetary Nebula are the outer layers of a star that are lost when the star changes from a red giant to a white dwarf. A star is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). They are born from nebulae and consist mostly of hydrogen and helium gas.
What else can I help you with?
What characteristic determines the life cycle of a star?
mass
What are the star life cycle that are accurate?
The stages in a star's life cycle are: formation from a nebula, main sequence (where it fuses hydrogen into helium), red giant or supergiant phase, depending on the star's mass, and finally either collapse into a white dwarf, neutron star, or black hole. This life cycle is accurate for most stars, including our Sun.
Where does a supernova fit into a star's lifecycle?
A supernova occurs at the end of a massive star's life cycle.
What is a stellar cycle?
A stellar cycle refers to the regular pattern in which a star goes through various stages of its life, such as the changes in energy output, size, and temperature over time. This cycle is influenced by the star's mass and can involve phases like main sequence, red giant, and white dwarf stages. The Sun, for example, is currently in the middle of its stellar cycle as a main sequence star.
When or where does the dead star happen?
"Dead star" is a term used to describe various astronomical phenomena related to dying stars, such as white dwarfs, neutron stars, or black holes. These occur as stars reach the end of their life cycle and can be found throughout the universe.
How can you describe the life cycle of a star?
size and diameter
What is the star life cycle of the sun?
Life cycle of a sun like star. A sun like star will start out as a nebula to a protostar to a main sequence star to a red giant and into a white dwarf and will simply fade out.
What is the life cycle of the star capella?
What is capella star life cycle
Where is the earth on the star life cycle?
The "star life cycle" refers to stars. Earth is not a star.
How can solar radii be used to describe the sizes of stars?
this is simple its used to describe the star sizes through a process that is complicated and people see this through the life cycle of a star as the minerals inside the star change over time
Will a protostar form near the end of a star's life cycle?
No, a protostar is basically the BEGINNING of a star's life cycle.
compare your life to the life cycle of a star?
How does the life cycle of humans compare to the life cycle of a star? They both have stages where they are born and die which is in the main sequence and supernova and in a human they are born in a womb and die of old age.
Who invented the life cycle of a star?
Nobody "invented" it, the life cycle of stars happens naturally.
What does a life cycle of a star look like?
Nebule > Star > Red Giant > Red Dwarf > White Dwarf > Supernova > Neutron Star > Black Hole.
Which of the following steps in a star's life cycle takes the longest?
The longest stage in a star's life cycle is the main sequence stage, where the star fuses hydrogen into helium in its core. This stage can last for billions of years for stars like the Sun.
Whats the life cycle of the stars?
A star's life cycle starts from a nebula. For giant stars, the star turns into a huge star to a super red giant to a supernova to a black hole. A sun-like star turns to a red giant, then a planetary nebula, a white dwarf, and then a black dwarf.
What determines the life cycle of a star?
its mass
