    <description descriptionType="Abstract">&lt;pre&gt;&lt;em&gt;Context:&lt;/em&gt; 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.&lt;/pre&gt;

&lt;pre&gt;&lt;em&gt;Aims:&lt;/em&gt; 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. &lt;/pre&gt;

&lt;pre&gt;&lt;em&gt;Results:&lt;/em&gt; The &lt;strong&gt;EGGMiMoSA&lt;/strong&gt; (&lt;strong&gt;E&lt;/strong&gt;xtracting &lt;strong&gt;G&lt;/strong&gt;uesses about &lt;strong&gt;G&lt;/strong&gt;iants via &lt;strong&gt;Mi&lt;/strong&gt;xed-&lt;strong&gt;Mo&lt;/strong&gt;des &lt;strong&gt;S&lt;/strong&gt;pectrum &lt;strong&gt;A&lt;/strong&gt;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.&lt;/pre&gt;</description>
