He laid the basis of tidal theory, conceiving an "equilibrium tide
" that would apply to ideal conditions of a global ocean.
Astronomical tide (gravitational tide, equilibrium tide).
Equilibrium tide. Hypothetical tide due to the tide-producing forces under the equilibrium theory; also known as the gravitational tide.
Papers and discussions from the workshop describe recent work in areas such as dynamic tides and the evolution of stars in close binaries, eccentric eclipsing binary systems, and equilibrium tides
in differentially rotating stars.
