WebThe core of the star becomes a white dwarf. It moves to the lower left on the HR diagram; it is very hot, but low luminosity because it is very small. Gradually, with no fusion left to produce heat, the white dwarf cools off and dims, eventually becoming a black dwarf star.

WebOct 7, 2024 · As a star ages it moves through the HR-diagram on paths at different rates. Most of the star's lifetime is spent on the line where it burns hydrogen in its core, known as the "main sequence". As the fusing layer expands due to the growth of the inert core in the center, the star moves up and to the right (brighter and redder) on the diagram. Webon the H-R diagram over 10 mil-lion years. 4. As the rate of core fusion in-creases due to higher core tem-perature, the outward gas and ra-diation pressures eventually match the inward gravitational force.

"WebTherefore, astronomers often speak of a star moving on the H–R diagram, or of its evolution tracing out a path on the diagram. In this context, "tracing out a path" has nothing to do with the star’s motion through space; this is just a shorthand way of saying that its temperature and luminosity change as it evolves.

WebSep 20, 2024 · How do stars move through the H-R diagram? When stars have exhausted all their hydrogen fuel, they evolve to red giants. Their outer layers of gas expand and cool; therefore, the stars move to the right on the H-R diagram. Therefore, the star also moves up the H-R diagram. WebThe Plotted Stars panel allows you to add various groups of stars to the diagram. The Cursor Properties panel has sliders for the temperature and luminosity of the active location on the HR Diagram. These can control the values of the active location or move in response to the active location being dragged.
