What factor determines the lifespan of a star?
MASS
Which two factors determine the characteristics of a star?
The two main factors that determine the characteristics of a star are its mass and its age. The mass of a star determines its temperature, size, luminosity, and lifespan. A star's age affects its stage in its life cycle, such as whether it is a young, main-sequence star or an older red giant.
What are most stars made of and how does their composition affect their characteristics and lifespan?
Most stars are primarily made of hydrogen and helium. The composition of a star affects its characteristics and lifespan because the fusion of these elements in the star's core produces energy through nuclear reactions. The balance between the outward pressure from nuclear fusion and the inward force of gravity determines the star's size, temperature, brightness, and how long it will live.
What determines color of the stars?
The temperature determines the color of the star!:)
What determines how large a star a star will become?
Initially it is a question of how much material was present in the disk that collapsed to form the star. Subsequently, it may be affected by collisions with nearby stars.
What Inside a star the force of gravity is balanced by the?
Inside a star, the force of gravity is balanced by the pressure generated from nuclear fusion reactions occurring in the star's core. These nuclear reactions create an outward pressure that counteracts the force of gravity trying to collapse the star. This delicate balance between gravity and pressure determines the size, temperature, and lifespan of a star.
What factor determines if a neutron star forms or a black hole forms after a supernova explosion?
The factor that determines whether a neutron star or a black hole forms after a supernova explosion is the mass of the collapsing core of the star. If the core's mass is between about 1.4 and 3 times the mass of the sun, a neutron star is formed. If the core's mass exceeds about 3 solar masses, a black hole is likely to form.
What determines if a star will be a white dwarf or neutron star?
Its Mass.
What one thing determines where a star is plotted on the main sequenxe?
The one thing that determines where a star is plotted on the main sequence is its mass. A star's mass influences its temperature, luminosity, and lifespan, which are key characteristics that define its position on the Hertzsprung-Russell diagram. More massive stars are hotter and more luminous, appearing on the upper left of the main sequence, while less massive stars are cooler and dimmer, located on the lower right.
Why is a star's birth mass its most fundamental property?
A star's birth mass determines its temperature, luminosity, size, and lifespan. These properties dictate the evolutionary path the star will take, influencing its appearance, behavior, and eventual fate. Therefore, a star's birth mass is considered its most fundamental property as it plays a crucial role in shaping its entire life cycle.
What characteristic determines if a star will end its life as a black hole or neutron star?
The mass of the star.
What determines the life cycle of a star?
its mass
