Solar astronomy is a lecture and an article about astronomy of Sol.

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, and in the {{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.

A suggestion is to 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
