  <dc:description>Context: Owing to the detection of mixed-modes, subgiant and red-giant stars provide a unique opportunity to probe the complete stellar structure of solar-like stars and to constrain stellar structure and evolution models.

Aims: Taking advantage of the asymptotic description of mixed-modes, we develop a method that coherently accounts for the complex oscillation spectra of subgiant and red-giant stars. We investigate the probing potential of this technique and define robust seismic indicators, relevant of the stellar structure in order to constrain stellar models. 

Results: The EGGMiMoSA (Extracting Guesses about Giants via Mixed-Modes Spectrum Adjustment) method is fast (less than a second execution) and allows to study the evolution of the typical mixed-modes spectra parameters along a grid of models ranging from the subgiant to the red-giant phases.</dc:description>
