  "description": "<pre><em>Context:</em> 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.</pre>\n\n<pre><em>Aims:</em> 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. </pre>\n\n<pre><em>Results:</em> The <strong>EGGMiMoSA</strong> (<strong>E</strong>xtracting <strong>G</strong>uesses about <strong>G</strong>iants via <strong>Mi</strong>xed-<strong>Mo</strong>des <strong>S</strong>pectrum <strong>A</strong>djustment) 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.</pre>",
