Chapter 17, Problem 17EAP
Does It Make Sense?
Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly; nor all of these have definitive answers, so your explanation is more important than your chosen answer.

Based on what you learned about the source of stellar energy and how stars make energy, select all of the correct statements from the following list.
1. Many stars make energy with the proton-proton cycle.
2. The CNO cycle is more efficient than the proton-proton cycle.
3. The sun's energy comes from the CNO cycle.More massive stars make energy with the proton-proton cycle.
4. The leftover mass in both the proton-proton cycle and the CNO cycle is converted to energy.
5. A helium atom is more massive than four hydrogen atoms.
6. The CNO cycle requires a higher temperature than the proton-proton cycle.
True or False
8. Almost all stars are in binary systems. The book says: "So far you have been considering the deaths of stars as if they were all single objects that never interact, but more than half of all stars are members of binary star systems."From this, I would not necessarily say that almost all stars are in binary systems based on this alone, but some other information I am finding says up to 85%. However, the numbers seem to be all over the map outside the course material, and I can not find a solid figure in it from what I have looked at.
If it helps, Stars and Galaxies, 10th Edition by Seeds and Beckman is my reference material.
Nuclear fusion is a process which releases large amounts of energy and takes place in the core of stars like our Sun.
1a) Describe what is meant by nuclear fusion and the conditions necessary for it to take place.
b) It is believed that the first elements to exist in the early Universe were hydrogen and helium. What role has nuclear fusion taken in the creation of the world around us?

- PLEASE MAKE SURE THAT YOU ARE ANSWERING THE QUESTIONS USING YOUR OWN THOUGHTS. STRICTLY NO COPY PASTE PLEASE! Answer each questions in not less than 2 paragraphs: 3. What is astronomy? 4. What is Geocentric Model?arrow_forwardBased on what you learned about stellar evolution, select all of the correct statements from the following list. 1. The period of some Cepheid variables actually changes. 2. When getting dimmer, variable stars are releasing energy; when getting brighter they are storing energy. 3. variable stars are expanding and contracting 4. despite their variability, variable stars stay in a specific position on the H-R diagram. 5. A changing period in a Cepheid variable means that the size of the star is changing and that the star is therefore evolving. 6. Only stars on the instability strip are variable. 7. More massive stars will vary their brightness more quickly.arrow_forwardAnother explanation for the Universe is the Steady State Hypothesis. The Steady State Hypothesis says that the Universe has always existed and is infinite in extent. Which of the following supports the Big Bang Theory and which supports the Steady State Model. (Select B-Big Bang Theory, S-Steady State Model, If the first is B and the rest S, enter BSSSSS). A) An observation that some globular clusters show M-type stars that have evolved off the main sequence. B) The measurement of redshifts that show galaxies appear to be moving away from each other and the Universe is expanding. C) A measurement that shows the density of the Universe is close to the critical density. D) The measurement of the microwave background radiation. E) Observing that galaxies at very large distances look identical to those in the nearby universe.arrow_forward
- Please help. I don't know how to set up the correct components on yhe diagram and I'm unsure on how to answer the this question.arrow_forwardAstronomy Briefly explain what evidence we can use to learn about the lives of stars even though their lives are far longer than human lives. Why do HR diagrams look different for star clusters of different ages? How do we use the diagram to determine the age of the cluster? How can we estimate how much longer the lifetime of a low-mass star is than the lifetime of a high-mass star? How do we use parallax to measure the distance to stars? Explain the inverse square law for light. If we know the distance to a star, how do we find its luminosity? If we know the luminosity of a star, how do we find the distance? What are apparent magnitude and absolute magnitude? How do they relate to apparent brightness and luminosity? What is meant by spectral type? What spectral type is the hottest? Which is the coolest? What is meant by luminosity class? What are the three basic types of binary stars?arrow_forward1. The discovery of Cosmic Background Radiation helped explain...a.

- Why are we unlikely to find Earth-like planets around halo stars in the Galaxy? A. Halo stars formed in a different way from disk stars. B. Planets around stars are known to be extremely rare. C. Halo stars formed in an environment where there were few heavy elements to create rocky planets. D. Halo stars do not have enough mass to hold onto planets. Is the answer C? Since halo stars are formed early when the galaxy consisted of mainly hydrogen and helium, there are no heavier elements available to create Earth-like planets so just halo stars are formed? Thanks!arrow_forwardA star's Zero Age Main Sequence (ZAMS) radius R, luminosity L, and effective temperature Teff depend primarily on the star's mass.
