You are free to take this quiz based on solar astronomy at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the {{radiation astronomy resources}} template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

9 Red-giant stars have (or theoretically may have) these in common:

	potential 22Ne
	helium-burning shells
	non-standard neutrino losses
	Lithium red line
	N stars display F abundances up to 30 times the solar system value
	RGB and AGB stars
	a radius between 200 and 800 times that of the Sun

10 True or False, Some observed properties of the Sun still defy explanation, such as the degree of Li depletion: the solar Li abundance is roughly a factor of 200 below the meteoritic abundance. This has been confirmed using the lithium 555.2 nm line.

	TRUE
	FALSE

11 Which of the following is not a phenomenon associated with red astronomy?

	a stellar class M dwarf
	the hydrogen Balmer alpha line
	the photosphere of the Sun
	an emission with a wavelength of 618 nm
	lithium
	"cometary knots"

12 True or False, Stars of spectral classes F and G, such as our sun, have color temperatures that make them look "greenish".

	TRUE
	FALSE

13 Complete the text:
