Hayashi track
The Hayashi track is a luminosity-temperature relationship obeyed by infant stars of less than Template:Solar mass in the pre-main-sequence phase (PMS phase) of stellar evolution. It is named after Japanese astrophysicist Chushiro Hayashi.On the Hertzsprung-Russell diagram, which plots luminosity against temperature, the track is a nearly vertical curve.Deutsch: Entwicklungswege von Sternen vor Eintreten in die Hauptreihe (deshalb Vorhauptreihensterne genannt; "Vorhauptreihe" = engl. "pre-main-sequence", kurz "PMS"). Für Entwicklungswege nach Eintreten in die Hauptreihe siehe Category:Stellar evolutionary tracks.

While on the Hayashi track, a star is largely or completely in convective equilibrium.

I summarize the status of pre-main-sequence evo Because of this, the small stars that develop this way are said to follow the "Hayashi track" rather than the "main sequence" of development that most stars follow. Besides this monumental contribution to our understanding of stars, Hayashi discovered a limit to how big a star can get, depending on its mass, which is called the Hayashi ...Stars change their positions on the HR diagram throughout their life. Newborn stars of low or intermediate mass are born cold but extremely luminous. They contract and dim along the Hayashi track, decreasing in luminosity but staying at roughly the same temperature, until reaching the main sequence directly or by passing through the Henyey ... 94 M.

At the end of the Hayashi track, a protostar isn't quite ready to begin hydrogen fusion and join the main sequence. It has to get hotter first. It turns out that Henyey wasn't completely wrong when he proposed that protostars increase in luminosity as they form; that is, the last portion of the Figure 2 track aligns with the tracks in Figure 1.What do astronomers call the evolutionary track on the HR diagram that describes the formation stages of stars with mass less then 2.5 MSun?

Rapid rotation tends to ...Hayashi track develop high enough temperatures at the base of the SCZ so that energetic protons destroy Li there, thereby de-pleting the surface Li abundance. Lower stellar mass implies a deeper and longer-lived SCZ, which implies more Li depletion; there is little Li depletion for models reaching the zero-age main sequence (ZAMS) as A, F, and G …
Henyey track. The Henyey track is an almost horizonta Hayashi limit is a theoretical constraint upon the maximum radius of a star for a given mass. When a star is fully within hydrostatic equilibrium —a condition where the inward force of gravity is matched by the outward pressure of the gas—the star can not exceed the radius defined by the Hayashi limit. This has important implications for ...A trilha de Hayashi é o trajeto das protoestrelas no diagrama de Hertzsprung-Russell após o momento em que a nuvem protoestelar se aproximou do equilíbrio hidrostático.

Address for correspondence: T Hayashi, Department of Human Patholog Earth Sciences questions and answers. The Sun took 30 million years to evolve from a collapsing cloud core to a star, with 10 million of those years spent on the Hayashi track.
