Imagine that you are observing a star and you
find the
wavelength of peak emission for the star to be
400 nm.
What would the wavelength of peak emission
be for a
new star that has a surface temperature that
is a
quarter of the original star?
Using the same pair of stars from the first
question,
●
how does the luminosity (the energy output) of
each
star compare if we assume that both stars are
the
same size? (Please provide a specific factor or
proportion)
What type of radiation/light (from the
electromagnetic
spectrum) is each star emitting?
Now imagine that we determine that the
wavelength of
peak emission of the original star was
determined to
be bluer than it should be based on other
observations. Would this indicate that the star
is
moving towards us or away from us relatively
speaking
through space?
0
a) To which object corresponds this spectrum to?
b) What is the source of radiation for each of the two humps?
c) Why does the hump on the right hand side peak at higher wavelength than the hump on the left? [Specifically, what does this tell you about the temperature for each object that the light originates from?]
