The life cycle of a star is determined primarily by its mass. The hotter a star the bluer its color. The difference between apparent brightness and luminosity is that luminosity is a good indicator of the energy output of a star.
The most important factor is the stars mass.
rrrrr
The life cycle of all stars is pretty similar from birth to late in their life - that's when the rest of their life cycle can vary dramatically. Small and medium-sized stars tend to be the longest-lived stars (our Sun is a typical example), and they end their life by expanding, cooling, and then blowing off their outer shell while their nucleus collapses to a "White Dwarf".
Mass and size
Short, violent, and ends as a black hole.

Mainly their mass.
1) Planning for property, 2) Acquiring property, 3) Managing property, and 4) Disposing of property.
The mass of a star determines how it ends its life cycle. Less massive stars become white dwarfs, shedding their outer layers as glowing shells of ionized gas (planetary nebulae). Stars 10+ times more massive than the Sun can be rendered as supernovae, as their cores collapse into black holes.
The "star life cycle" refers to stars. Earth is not a star.
Nobody "invented" it, the life cycle of stars happens naturally.
In the nebula!
Stars go through stages like birth, main sequence, red giant, and death, which can last millions or billions of years. In comparison, humans have a much shorter life cycle, typically living for decades. Both stars and humans undergo changes over time and eventually cease to exist.
The smaller a star is, the longer its life cycle.
the answer is a protostar
The more the mass the shorter their life cycle (the more quickly they use their fuel)
