The picture shows the spectra of two objects observed with a new telescope

For each object (A and B), state if it is a star and why or why not?

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?
The 305-m diameter Arecibo radio telescope (located in Puerto Rico) is shown below, prior to its unfortunate recent collapse. Approximately how close on the sky could two radio stars be located while still being distinguishable as separate stars by Arecibo? Assume radio waves of frequency 1420 MHz (the famous atomic hydrogen line). 17 arcsec 17 arcmin 29 arcmin 2.9 arcmin 17,000 arcsec
A certain star has a (B-V) color index of 0.61 and a B magnitude of 6.87. How many times brighter is this star when measured using a V filter than when using a B filter?

Earth tugs the Sun around as it orbits, but it affects the radial velocity of the sun by only 0.09m/s. How large a shift in wavelength does this cause in the Sun's spectrum at 575 nm?
If Star A's temperature is 5000 K and Star B's wavelength of peak emission is 5/7 as long as that of Star A, what is the temperature of Star B (in K; don't write the units in the text box)?
(Answer don't copy with hand written please)As a star runs out of hydrogen to fuel nuclear fusion in its core, changes within the star usually cause it to leave the main sequence, expanding and cooling as it does so. Would a star with a radius 12 times that of the Sun, but a surface temperature 0.5 times that of the Sun, be more, or less luminous than the Sun? Show and explain your reasoning. You may assume the surface area of a sphere is A = 4πr2.
