These objects hypothetically lie above the boundary for hydrostatic equilibrium.
This causes the water level in a well to rise to a point where hydrostatic equilibrium has been reached.
The first equation represents hydrostatic equilibrium and the second mass conservation.
Both models treat the white dwarf as a cold Fermi gas in hydrostatic equilibrium.
However, precise regulations as to how hydrostatic equilibrium would be measured were left undefined for the time being.
More specifically, its own gravity should pull it into a shape of hydrostatic equilibrium.
The state of balance is called hydrostatic equilibrium.
However, there is no one point at which an object can be said to have reached hydrostatic equilibrium.
The Henyey track is characterized by a slow collapse in near hydrostatic equilibrium.
Consider a column of water in hydrostatic equilibrium.
