I've clicked on the star HD 195850, HD 195850 which is of spectral type 'F5IV;' this means its Spectroscopic binary spectral type is F.

Include them if you can. Do they look the same as yours? In your Figure 2, we have zoomed in on a portion of the spectrum from your Figure 1, specifically, the wavelength region from 400 nm to 700 nm. There are a variety of absorption features visible caused by various elements (they are visible in Figure 1 as well, but harder to see because it's so zoomed out). 7. [3 marks] Using the known absorption patterns for a variety of elements, identify the three (3) elements that are responsible for your star's absorption features (each student's spectrum has absorption features from exactly 3 elements, no more, no less). 8. [2 marks] In the previous question, there was no relative motion between the star and Earth. Redraw your Figure 2, but for the case the star is moving very quickly towards us. Redraw your Figure 2 one more time, but for the case the star is moving very quickly away from us. 9. [3 marks] In the previous questions, you identified a set of three elements that are responsible for the absorption features seen in your star's spectrum. Let's imagine a nebula (cloud of gas) in space that is made up of exactly those three elements. Draw an emission spectrum that matches that description. (You could start by copying the axes of Figure 2 into a new Figure 3 for yourself to work from).
