Kumar, S.S., 1963: The Helmholtz-Kelvin time scale for stars of very low mass. Astrophys. J., 137, 1126-1128, doi:10.1086/147590.
Assuming that the contracting stars in convective equilibrium evolve vertically downward in the H-R diagram, a simple expression for the Helmholtz-Kelvin time scale tHK is derived. Application of this expression to stars of mass M < 0.1M☉ shows that these stars contract to a radius of about 0.1R☉ in a time scale of approximately 1 billion years, while the earlier estimates, based on horizontal evolution, gave a time scale tHK greater than a hundred billion years.
