WebNov 12, 2014 · In the Hertzsprung–Russell (HR) diagram , i.e. the log T eff —log L diagram, where T eff is the surface temperature of a star and L its bolometric luminosity, this results in the protostar departure from the so-called Hayashi track. The latter is defined as the evolutionary path traced by a fully convective structure in hydrostatic equilibrium. WebSuch an excursion across the HR diagram is very rapid, lasting no more than a few thousand years. As a consequence, stars undergoing this type of shell‐burning instability are rarely observed. (See Figure 4.) Figure 4. HR …
