Meaning of Hayashi limit | Babel Free
Definitions
A theoretical maximum radius of a star of given mass; the radius at which the inward force of gravity exactly balances the outward pressure of the gas of the star.
Equivalents
Examples
“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⟳.^([Wikipedia])”
“However, the approximate locations of the Hayashi limits point⟳ to remarkably low masses for the three T Tauri stars investigated here. It should be noted, that the Hayashi limits are valid only for stars in hydrostatic equilibrium.”
“Since the Hayashi limit⟳ approaches close⟳ to the main sequence at about 1 M⊙, the 'Hertzsprung gap' between the terminal main sequence and the Hayashi limit⟳ is much less marked than at high masses.”
“The latest-type RSGs^([Red Supergiants]) in the Magellanic Clouds are cooler than the current evolutionary tracks allow⟳, occupying the region to the right of the Hayashi limit⟳ where stars are no longer in hydrostatic equilibrium.”
