- 2If the Sun was producing its energy by slow contraction as suggested by Helmholtz and Kelvin, estimate the amount by which the radius of the Sun has to decrease every year to produce the observed luminosity.We will take a moment to compare how brightly a white dwarf star shines compared to a red giant star. For the sake of this problem, lets assume a white dwarf has a temperature roughly twice as large as a red giant star. As for their stellar radii, the white dwarf has a radius about 1/10000th that of a red giant star. With this in mind, how does the luminosity of a red giant star compare to that of a white dwarf? (Put differently, find the ratio of their luminosities a.k.a. how many times more luminous is the red giant than the white dwarf? An answer of less than 1 means the white dwarf is more luminous, an answer of 1 means they have the same luminosity, and an answer greater than 1 means the red giant is more lu
- Using Wien's Law for two black body objects with a temperature of 1000 K (fire) and 290 K (background), at what central wavelengths are the two objects radiating?Hi, I have the answer for this question but I'm not sure how it was done. I worked it out on paper and ended up with 1.3 x 10^1 Could you please explain in as much detail each step to get to the answer becasue I'm confused about where I went wrong since I was able to get everything except for the correct power.Describe the plysical environment and processes to obtain the emission line spectra and absorption line spectra from the stars.

- Explain the meaning of each symbol in the equation COS [ 27 (1 - :)] T y = A cos and summarize how we devised this equation.An interstellar cloud is observed at a wavelength of 2.898 µm. Estimate the temperature of the cloud.The three most prominent spectral lines of hydrogen are H-α at 656 nm, H-β at 486 nm, and H-γ 434 nm. If we observe an object with H-α at a wavelength of 700 nm, what wavelength will we observe H-β and H-γ? Is the object moving toward or away from us, and how do you know? Suppose we observe another object with H-α at 585 nm. Is this object moving toward or away from us? Is it moving slower or faster than the first object?
