Expert Solution & Answer

Answer to Problem 1QP

Options (c).

Explanation of Solution

High-mass stars are stars with masses greater than about eight times mass of the Sun. As a high-mass star evolves, it builds up a layered structure like that of an onion, with progressively more advanced stages of nuclear fusion found deeper and deeper within the star.

As the high-mass star leaves the main sequence, the core will begin to collapse and the carbon fusion will occur. Carbon fusion will produce more massive elements including oxygen, sodium, neon and magnesium. The star then will have a carbon fusing core surrounded by a helium-fusing shell surrounded by a hydrogen-fusing shell, which moves outward as fusion products accumulate in the core. When carbon is exhausted as a nuclear fuel at the center of the star, neon breaks down to oxygen and helium or fuses to magnesium; and when neon is exhausted, oxygen begins to fuse. Thus, the residue of one reaction becomes the fuel for the next as the star evolves a layered structure like that of onion.

Conclusion:

Since a high-mass star develops a layered structure as a result of the heavier atoms fuse closer to the center because the high pressure and temperature available there, option (c) is correct.

1. A star on the main sequence has a surface temperature of10,000 K. Use the H-R diagram to determine it’s luminosity(approximately) and then calculate it’s mass and age (you mayuse solar units). If it were a red giant, could we do this?

As a cluster of stars begins to age, which type of star in the cluster will move off the main sequence of the H-R diagram first? 1) all the stars in a cluster are born at the same time; so they will all move off the main sequence at the same time, as they evolve 2) G type stars, like our Sun 3) M type stars, which are the coolest 4) the lowest mass stars, which have the least amount of fuel for fusion 5) the O and B type stars

1. A star with an original mass of 9MSun undergoes an active period where it experiences mass loss via a super-wind over 1.1 million years. Its new mass is 3MSun. What was the mass-loss rate each year the super-wind was active? (Enter your answer in MSun/yr.)
