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 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

Research

Hypothesis:

  1. Astronomy of the Sun includes the radiation astronomy of the astronomical object often called the Sun.

Control groups

This is an image of a Lewis rat. Credit: Charles River Laboratories.

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[1] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[2]"[3]

Proof of concept

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[4] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[5]
