Prior Noesis Questions (Do these BEFORE using the Gizmo.)

one. The epitome at left shows three stars in the constellation

Orion: Betelgeuse (A), Mintaka (B), and Rigel (C). How do

the appearances of stars A, B, and C compare?

Star C is larger than stars A and B and Star A is a

different colour and then stars B and C.

2. What are some ways the stars in the photograph could be grouped

or classified?

Stars can be classified past colour, size and luminosity

(effulgence)

Gizmo Westarm-upwardly

In the early 1900s, astronomers identified many star

characteristics such equally colour, size, temperature, and luminosity

—or how bright a star is. Using the H-R Diagram Gizmo, you lot volition

detect how some of these characteristics are related.

Start by moving your cursor over the stars in the Star

collection. Star information is displayed on the correct side of the

Gizmo. The numbers given for Luminosity, Radius, and Mass

are in comparison to the Sun. And so, a star with a radius of "2

Suns" is twice as large as the Sun. Temperature is given using

the Kelvin calibration, where 273.xv K = 0 °C and 373.15 M = 100 °C.

i. Observe Betelgeuse in the Star drove. Fill out the

chart at correct.

3,400 K

2. The Sun has a radius of 695,500 km.

What is the radius of Betelgeuse? 383.4 million mi
