Quizplus · Accepted Answer

The instability strip includes stars that have left the main sequence and are evolving to become giants or supergiants. Main sequence stars are not included in this category, as they are not undergoing significant changes in luminosity due to interior changes. The instability strip includes stars that are evolved beyond the main sequence, such as subgiants, giants, and supergiants. Main sequence stars are not within the instability strip.
