Toomre diagram for the all stars in the CHEPS sample. The space rotation velocity V vs. [Fe/H] and vs. stellar age. The solid lines show constant values of the total space velocity, Vtot = (U2 + V2 + W2)1/2, at 50 and 100 km s−1. Our stars are marked in red, HIP 51987 and HD 128358 are shown as large and small blue squares, and the Sun is plotted in green.
