5 Multiple choice questions
- The distance to an object with a parallax angle of 1 arcsecond; unit is pc. One pc = 3.26 light years (ly) = 3.09 x 10^13 km.
- Pale Blue -Temperature range: 10,000 - 30,000 K
- One of the major classes of variables.
- Spectral type M (red) Temperature range <3,500 K.
- If we see a star at twice the distance, we see 1/4 the amount of light. If the star is at 10 times the distance, we would see 1/100 the amount of light.
5 True/False questions
Solar Luminosity → A Star's total amount of power radiated into space; measured in watts
Sirius → Spectral type A (aqua) Temperature range: 7,500 - 10,000 K
Spectral Type → Stars color/surface temperature E - this is how we classify stars.
Arcturus → Spectral type F (pale yellow) Temperature range: 6,000-7,500 K.
Open Cluster → The distance to an object with a parallax angle of 1 arcsecond; unit is pc. One pc = 3.26 light years (ly) = 3.09 x 10^13 km.
