Abstract
Stars undergo evolution during their lifetime, from protostars to white dwarfs. During this process, many parameters affect the evolution of stars, including overshooting and rotation. Adding variations in overshooting and rotation parameters to stellar evolution will result in different evolutionary tracks. The addition of overshooting and rotational effects has a similar effect on global star parameters, both processes resulting in increased luminosity and extended main sequence lifetimes.
Overshooting and rotation affect the evolutionary path of intermediate mass stars, especially in the length of the blue loop line, which increases in the RGB phase. The addition of the overshooting and rotation also affects the luminosity, mass changes, interior composition, and age of the star. Using Linux-based MESA with the release series r12778, stellar evolution calculation will be carried out to review the effect of overshooting and rotation on the evolution of intermediate-mass stars with defined parameters.
