What is the relationship between mass and size of stars?

In general, bigger the mass of the dense core, the more massive the star that is born from it. This is simply because the star has more material to accrete from.

What is the relationship between the age of a star and its mass?

The overall lifespan of a star is determined by its mass. Since stars spend roughly 90\% of their lives burning hydrogen into helium on the main sequence (MS), their ‘main sequence lifetime’ is also determined by their mass.

What is the relationship between star mass and luminosity?

The luminosity and temperature of a main-sequence star are set by its mass. More massive means brighter and hotter.

How long will it take a larger mass star to reach the main sequence?

While the sun will spend about 10 billion years on the main sequence, a star 10 times as massive will stick around for only 20 million years.

What is the relationship between the mass of a star and how long the star will live quizlet?

What is the relationship between the mass of a star and how long the star will live? Higher mass stars live shorter lives.

What is the relationship between a stars mass and luminosity?

How are mass and luminosity related quizlet?

What is the mass-luminosity relationship? The larger a star’s mass, the larger its luminosity is.

What is luminosity of a star?

Another measure of brightness is luminosity, which is the power of a star — the amount of energy (light) that a star emits from its surface. It is usually expressed in watts and measured in terms of the luminosity of the sun.

What is the relationship between a star’s mass and luminosity?

What is the relationship between the mass of a star and its rate of formation quizlet?

What is the relationship between the mass of a star and its rate of formation? High-mass stars form more quickly than low-mass stars.

What is the relationship between mass and luminosity of stars on the main sequence?

When the luminosity of main sequence stars is plotted against their masses, we observe a mass‐luminosity relationship, approximately of the form L ∝ M 3.5 (see Figure ). In other words, doubling the mass of a main sequence star produces an increase in luminosity by a factor 2 3.5 = 11 times.

Which sentence describes the relationship between mass and luminosity of stars on the main sequence?

Which sentence describes the relationship between mass and luminosity of stars on the main sequence? The larger the stellar mass, the larger the luminosity.

What determines the lifespan of a star on the main sequence?

Main Sequence Lifetime The overall lifespan of a star is determined by its mass. Since stars spend roughly 90\% of their lives burning hydrogen into helium on the main sequence (MS), their ‘ main sequence lifetime ’ is also determined by their mass.

What is the relationship between mass and luminosity in the main sequence?

Since the Main Sequence is also a sequence in luminosity—that is, O stars are the most luminous, then B, then A, F, G, K, and M stars are the least luminous—there must be a relationship between mass and luminosity.

What happens to the mass of a star when it cools?

Eventually, only about 20\% of the star�s initial mass remains and the star spends the rest of its days cooling and shrinking until it is only a few thousand miles in diameter. It has become a white dwarf. White dwarfs are stable because the inward pull of gravity is balanced by the electrons in the core of the star repulsing each other.

What is the most massive star in the main sequence?

O stars are the most massive, then B stars, then A, F, G, K, and M stars are the least massive. Since the Main Sequence is also a sequence in luminosity—that is, O stars are the most luminous, then B, then A, F, G, K, and M stars are the least luminous—there must be a relationship between mass and luminosity.
