Question

The diagram shown is an H-R (Hertzsprung-Russell) diagram illustrating the life track of a 1-solar-mass star with various stages labeled A through E.

The diagram features a graph where the x-axis represents "Temperature" (decreasing towards the right), and the y-axis represents "Luminosity" (increasing upwards). The path taken by the star throughout its life is delineated on the graph, moving through stages labeled A, B, C, D, and E.

Stages:
- **A**: The initial position on the graph.
- **B**: The star has increased in both temperature and luminosity.
- **C**: There is a decrease in temperature but an increase in luminosity.
- **D**: The track slightly loops, showing a temporary change in course.
- **E**: The star reaches its highest luminosity and lower temperature compared to previous stages.

Below the diagram, a question is posed: "What will happen to the star after stage E?"

Options provided are:
- A. It will gain mass until it collapses under its own weight.
- B. It will begin burning carbon in its core.
- C. It will explode in a supernova.
- D. It will collapse to make a neutron star.
- E. It will eject a planetary nebula.

2GM What is the escape velocity (in km/s) from the surface of a 1.1 Mo neutron star? From a 3.0 M, neutron star? (Hint: Use the formula for escape velocity, V. = make sure to express quantities in units of meters, kilograms, and seconds. Assume a neutron star has a radius of 11 km and assume the mass of the Sun is 1.99 x 1030 kg.) 1.1 Me neutron star km/s 3.0 M. neutron star km/s
1. A planetary nebula has an angular diameter of 76 arc seconds and a distance of 5100 ly. What is its linear diameter (in ly)? Hint: Use the small-angle formula: angular diameter (in arc seconds) 2.06 ✕ 105 = linear diameter distance 2. Suppose a planetary nebula is 3.2 pc in diameter, and Doppler shifts in its spectrum show that the planetary nebula is expanding at 31 km/s. How old is the planetary nebula in yr? (Note: 1 pc = 3.1 ✕ 1013 km and 1 yr = 3.2 ✕ 107 s.)
