1. The relative velocities of four stars are shown in the figure below with arrows.
If an astronomer were to study the light from these four stars, in which star would the astronomer see greatest redshift of its light spectra? Hint: Think Doppler Effect
A. star 1B. star 2C. star 3D. star 4
3. Name the 2 astronomers that discovered these relationships (star's luminosity, temperature, absolute magnitude and spectral class)
The spectral type of a star is directly related to its color. Recall that a star emits light as a blackbody, which has a particular shape to its spectrum, as shown in this figure. Based on this, what basic property of a star determines its color (and thus its spectral type)?

A. age
B. composition
C. radius

- Name five characteristics of a star that can be determined by measuring its spectrum. Explain how you would use a spectrum to determine these characteristics.arrow_forwardSpectral types are an indicator of temperature. For the first 10 stars in Appendix J, the list of the brightest stars in our skies, estimate their temperatures from their spectral types. Use information in the figures and/or tables in this chapter and describe how you made the estimates.arrow_forwardExplain what dispersion is and how astronomers use this phenomenon to study a star’s light.arrow_forward
- Astronomers recently detected light emitted by a supernova that was originally observed in 1572, just reaching Earth now. This light was reflected off a dust cloud; astronomers call such a reflected light a “light echo” (just like reflected sound is called an echo). How would you expect the spectrum of the light echo to compare to that of the original supernova?arrow_forwardChoose 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.arrow_forwardA. Arrange the following stars in order of increasing temperature: Red, white, blue, yellow red100 billion stars Galaxies are the biggest groups of stars and can contain anywhere from a few million stars to many billions of stars.

- 3) indicate which locations in the H-R diagram correspond to places where the evolution is slow. Answers should be in the order they occur in the star. For example, if, in order, E, I and A are locations where there is a long time between changes, then enter EIA. (HINT: There are exactly three of them Hint: Hint: Our sun will be stable for another 4 billion years and white dwarfs last a long time because they are small. Really good additional hint: There are 3 places where the evolution is slow.
