1) The Earth's orbital speed is approximately 30 km/s. A star emits a spectral line with 2=517.3nm. Over what range does the wavelength oscillate as the Earth orbits the Sun (if the star islocated at the ecliptic)?

The oscillation is set up due to the doppler effect.

Answered: 1) The Earth's orbital speed is…

The spectrum of the Sun has hundreds of strong lines of nonionized iron but only a few, very weak lines of helium. A star of spectral type B has very strong lines of helium but very weak iron lines. Do these differences mean that the Sun contains more iron and less helium than the B star? Explain.
A star has a peak output at 440 nm and has a luminosity of 3 solar luminosities. What is its radius? (LS=3.826 X 1026 J/s)
A star is known to be moving at 7.87km/s toward the earth. If you observe the spectral line to be at 9.63nm, at what wavelength would you expect to measure the spectral line in a lab? Please give your answer in nanometers and include 3 digits.
The a star system contains two stars, one with apparent magnitude m = 10.5 and the other with m = 10.9. What is the combined apparent magnitude of the two 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. Info below is what each of the labels are. 1) red giant, helium flash A2) white dwarf F3) red giant with helium burning shell B4) hydrogen fusion in shell around core I5) helium fusion in core D6) envelope ejected, planetary nebula H7) main-sequence star C8) helium used up, core collapses G9) hydrogen used up, core collapses E
