    <description descriptionType="Abstract">&lt;p&gt;Thanks to the high-quality data from space-based missions such as&lt;br&gt;
CoRoT, Kepler and TESS, great synergies between asteroseismology and&lt;br&gt;
exoplanetology were initiated and will further flourish with the future PLATO&lt;br&gt;
mission. Indeed, the exoplanets detection itself does not rely on&lt;br&gt;
stellar-model-dependent approaches and thus, a detailed characterization of&lt;br&gt;
the host star improves significantly the understanding of the exoplanet. In&lt;br&gt;
this context, we focused on Kepler-93, whose high-quality data and stellar&lt;br&gt;
properties make it a PLATO benchmark target and motivate a new&lt;br&gt;
characterization to reach their precision requirements. We carried out a&lt;br&gt;
detailed stellar modeling using global and local minimization techniques and&lt;br&gt;
considering various changes of the physical ingredients. We completed our&lt;br&gt;
analysis with inversion techniques to provide a more robust mean density&lt;br&gt;
estimate and test the impact of surface effects. The revised stellar&lt;br&gt;
parameters allowed us to update the planetary parameters of Kepler-93b and&lt;br&gt;
simulate its orbital evolution under the effects of tides and atmospheric&lt;br&gt;
evaporation. We found that a detailed asteroseismic modeling will be able to&lt;br&gt;
meet the PLATO standards for such a solar-like star.&lt;/p&gt;</description>
