Stars go through various stages in their life cycle, from being main sequence stars to becoming red giants. This article will explore the key points of these stages and provide insights into the fascinating evolution of stars.
What happens when a star runs out of hydrogen fuel?
When the hydrogen fuel in the core runs out, a star transitions from being a main sequence star to the next stage in its life cycle.
Why do red giants become variable stars?
Red giant stars can become variable stars due to oscillations between gas pressure and gravity, leading to changes in their luminosity.
How do red giant stars differ from main sequence stars?
Red giants are much larger than main sequence stars and undergo different fusion processes in their cores, leading to their distinct characteristics.
Can stars with more mass fuse heavier elements?
Yes, stars with more mass can fuse heavier elements beyond carbon and oxygen, leading to different evolutionary paths and characteristics.
What are the periods of variability for different types of variable stars?
Variable stars can have different periods of variability, such as less than 24 hours for RR Lyrae variables and 1 to 400 days for Cepheid variables.
