19 Οκτ 2016 · Stellar Evolution Powerpoint. This document discusses stellar evolution and how we observe stars across the universe. It notes that we can view stars forming, burning, and exploding using satellites and telescopes. The document also discusses the speed of light being 300,000 km/s and how we can observe stars millions or billions of light years ...

28 Ιουλ 2014 · Stellar Evolution • Red Giant Phase • Once a star begins burning helium in its core, it grows to become a red giant. • Red giants are so large because hydrogen continues to react in a thin layer at the edge of the helium core. The energy produced in this layer forces the outer layers of the star to expand.
Studying the stellar clusters and/or groups of stars with different masses, but with the same age. Studying the fast and strange phases in stellar lives (e.g. supernovae and novae). Through the study of variable pulsating stars, measuring the slow changes in the period of pulsation caused by their evolution.
Once a medium-size star has reached the red giant phase, its helium atoms fuse into carbon. The fusion releases energy, granting the star a temporary reprieve. The atomic structure of carbon is too strong to be further compressed by the mass of the surrounding material. No more fusion can happen.
