What are the three main characteristics used to classify stars

Asked by wiki @ in Chemistry viewed by 231 People

Which characteristics are used to classify stars on the Hertzsprung-Russell diagram? Check all that apply.

size
density
composition
temperature
absolute brightness

Answered by wiki @


Answer is: temperature
and absolute brightness.

The Hertzsprung–Russell diagram shows the relationship between the star's absolute luminosities (the total amount of energy emitted per unit of time by a star) versus their effective temperatures (the temperature of a black body that would emit the same total amount of electromagnetic radiation).

The Hertzsprung–Russell diagram puts each star on a graph according the star's brightness against its temperature.
