Models of rotating, 1 solar mass stars through the pre-main sequence and main sequence stages have been calculated. The calculations begin on the Hayashi track with rapid, rigid-body rotation, with angular momentum removed from the convective envelope to simulate the effect of the solar wind as the models evolve.

However, considerations of the conser- vation of angular momentum in the collapsing fragment indicate that it should form a rotating flat disk with a radius of several tens of astronomical units, much larger than a star would possess on the Hayashi track (Cameron 1962, 1963).

This has important implications for the evolution of a star, both during the formulative ...In the field of stellar evolution, a blue loop is a stage in the life of an evolved star where it changes from a cool star to a hotter one before cooling again.

The pre main sequence star (not protostar) is powered by the release of gravitational potential energy caused by its contraction. If the star is getting smaller at constant effective temperature, then of course it's luminosity ( ∝ R 2 T 4) decreases.Hayashi argued that this phenomenon could be explained as the last stage of the dynamical evolution of a star.

The Hayashi tracks have only a weak dependence on mass, with increasing mass shifting the vertical Hayashi track slightly to the left in the HR diagram. 2. The time for transition from fully convective to a radiative core has a strong dependence on mass, since in massive protostars the center heats up more rapidly and therefore becomes radiative more quickly.Title: New asteroseismic scaling relations based on Hayashi track relation applied to red-giant branch stars in NGC 6791 and NGC 6819.
