Below are sample questions representative of the exercises included on this worksheet and related 8.105 Star Properties and Classification (Introductory) skill assessments:

Problem 1Difficulty: Mastery

Which generalization best summarizes introductory star properties and classification?

AStar color tells only the distance to Earth, and size has no effect on brightness.

BAll blue stars are small and all red stars are large.

CH-R diagrams classify planets by moon count.

DStar color helps estimate temperature, and luminosity depends on both temperature and size; H-R diagrams organize these patterns.

Solution & Explanation:The skill connects color to temperature, brightness to luminosity and size, and H-R diagrams to star classification patterns.

Problem 2Difficulty: Mastery

Use the simplified H-R diagram with a marked target area. Which target area would best represent a cool, dim star?

ATarget A in the upper-left

BTarget B in the upper-right

CTarget D in the lower-right

DTarget C in the lower-left

Solution & Explanation:Cool stars are on the right side of many H-R diagrams, and dim stars are near the bottom, so cool and dim is lower-right.

Problem 3Difficulty: Mastery

A red star has luminosity 10000, and a blue-white star has luminosity 20. Which comparison is best supported?

AThe blue-white star is cooler but more luminous.

BThe red star is cooler but more luminous and likely much larger.

CThe red star must be hotter because it is brighter.

DBoth stars must have the same size because both are stars.

Solution & Explanation:Red color indicates cooler temperature, but the much higher luminosity suggests the red star is much larger.
