    Fusion
In summary, the time it takes for fusion to occur in a star is largely determined by its core temperature and mass. More massive stars have higher core temperatures and thus shorter fusion times, while lower mass stars have longer fusion times due to their lower core temperatures. However, the composition and density of a star can also play a role in the fusion rate and time. Understanding this difference in fusion times can provide valuable insights into the evolution and lifespan of stars, as well as the unique characteristics of different types of stars.

How many times longer does a 0.50 Msolar star fuse hydrogen at it’s core than dose a 1.5 Msolar star?

i just need the equation and i can figure it out. i can't find anything on google

thank you

I take it that you're on some sort of astronomy course and this is homework? The equation you are looking for can be easily derived by cosidering the fractions of mass that a star converts to energy and the luminocity of the star then comparing that with the values for our own star.
 

What is the difference in time for fusion to occur in a 0.50 and 1.5 Msolar star?

The time it takes for fusion to occur in a 0.50 Msolar star is significantly longer than in a 1.5 Msolar star. This is because the lower mass star has a lower core temperature and therefore lower fusion rate.

How does the mass of a star affect the time it takes for fusion to occur?

The more massive a star is, the shorter the time it takes for fusion to occur. This is because more massive stars have higher core temperatures and therefore higher fusion rates.

What is the main factor that determines the time for fusion to occur in a star?

The main factor that determines the time for fusion to occur in a star is its core temperature. The higher the core temperature, the faster the fusion rate and the quicker the star will consume its fuel.

Are there any other factors besides mass that can affect the time for fusion to occur?

Yes, the composition and density of a star can also affect the time for fusion to occur. Stars with higher densities will have higher fusion rates, while stars with different compositions may have different fusion reactions and rates.

What is the significance of understanding the time difference for fusion in stars?

Understanding the time difference for fusion in stars can provide valuable insights into the evolution and lifespan of stars. It can also help us understand the different types of stars and their unique characteristics based on their mass and composition.
