The star thus evolves rapidly to a stable state, beginning the main-sequence phase of its evolution. A new star will sit at a specific point on the main sequence of the Hertzsprung–Russell diagram, with …

Watch an animation of the stars in the Omega Centauri cluster as they rearrange according to luminosity and temperature, forming a Hertzsprung-Russell (H–R) diagram. To estimate just how much the …

Mar 23, 2026 · Outwardly the star shows no discernible effect, but the course of its evolution is changed with this new source of energy. Having only recently become a red giant, it now evolves somewhat …

The diagram demonstrates that normal stars like our Sun exist on what is called the Main Sequence. Other stars populate other areas based on the energy they produce and their luminosity.

The evolutionary track of a massive star loops back and forth across the diagram as it evolves. As the core runs out of each element, it contracts, heats up, and fusion starts again.

Nov 20, 2023 · Explore the evolution of stars: from the vastness of stellar nurseries to the death throes of supernovae and the enigmatic allure of black holes.

When studying the evolutionary tracks of stars, we often talk about how stars "move" in the HR diagram. Students can come away thinking that an HR diagram is like a map, and what the track plots is the …

Sep 28, 2023 · To unravel the birth and early evolution of stars and planets, we need to be able to peer into the hearts of dense and dusty cloud cores where star formation begins.
