Textbook Question
Chapter 5, Problem 16MOP
Two students are discussing their answers to Questions 14 and 15.
Student 1:I think Extrasolar Planet System C shows the star with the largest Dopplershift. This is because the star in System C has the largest orbit. Thismeans that this extrasolar planet will be the easiest to detect.
Student 2:I don’t think that Doppler shift is caused by the size of the star’s orbit. Tocause a large Doppler shift, you want a low-mass star that is close to alarge-mass planet, and that is Extrasolar Planet System B.
Do you agree or disagree with either or both of the students? Explain your reasoning.

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.
Choose the correct statements concerning spectral classes of stars. (Give ALL correct answers, i.e., B, AC, BCD...)
A) Neutral hydrogen lines dominate the spectrum for stars with temperatures around 10,000 K because a lot of the hydrogen is in the n=2 level.
B) Hydrogen lines are weak in type O-stars because most of it is completely ionized.
C) Oh Be A Fine Guy/Girl Kiss Me, is a mnemonic for remembering spectral classes.
D) The spectral sequence has recently been expanded to include L, T, and Y classes.
E) K-stars are dominated by lines from ionized helium because they are so hot.
F) The spectral types of stars arise primarily as a result of differences in temperature.

- The best parallaxes obtained with Hipparcos have an accuracy of 0.001 arcsec. If you want to measure the distance to a star with an accuracy of 10%, its parallax must be 10 times larger than the typical error. How far away can you obtain a distance that is accurate to 10% with Hipparcos data? The disk of our Galaxy is 100,000 light-years in diameter.

For Alpha Centauri, figure out how long the trip will take in years as well as in seconds.arrow_forward
- H II regions can exist only if there is a nearby star hot enough to ionize hydrogen. Hydrogen is ionized only by radiation with wavelengths shorter than 91.2 nm.
