Aims. We attempt to develop a new asteroseismic diagram and investigate its characteristics; based on the ratio r01 of adjacent; average; small separations.Methods. The ratio r01 is defined following the asymptotic formula of stellar p-modes. Using the low-degree; theoretical; numerical value of adiabatic frequencies of stellar model; we compute the ratio r01 and construct an additional asteroseismic diagram.Results. The additional asteroseismic diagram; which is similar to the C-D diagram (i.e. the famous asteroseismic HR diagram; so-called Christensen-Dalsgaard diagram); represents a composite of the average; large separations (Δv) and the ratio r01 of the adjacent; small separations. A distinct separation is identified between the effects of varying both mass and age. The diagram can therefore provide information that is complementary to that provided by a C-D diagram; which can be used to estimate directly both the stellar mass and evolutionary state. Interestingly; the age of star can be derived from the new asteroseismic diagram. Furthermore; we investigate the parameter r01; which can be a useful direct indicator of stellar age.. © 2008 ESO;
