  "abstract": "<p>Thanks to the high-quality data from space-based missions such as<br>\nCoRoT, Kepler and TESS, great synergies between asteroseismology and<br>\nexoplanetology were initiated and will further flourish with the future PLATO<br>\nmission. Indeed, the exoplanets detection itself does not rely on<br>\nstellar-model-dependent approaches and thus, a detailed characterization of<br>\nthe host star improves significantly the understanding of the exoplanet. In<br>\nthis context, we focused on Kepler-93, whose high-quality data and stellar<br>\nproperties make it a PLATO benchmark target and motivate a new<br>\ncharacterization to reach their precision requirements. We carried out a<br>\ndetailed stellar modeling using global and local minimization techniques and<br>\nconsidering various changes of the physical ingredients. We completed our<br>\nanalysis with inversion techniques to provide a more robust mean density<br>\nestimate and test the impact of surface effects. The revised stellar<br>\nparameters allowed us to update the planetary parameters of Kepler-93b and<br>\nsimulate its orbital evolution under the effects of tides and atmospheric<br>\nevaporation. We found that a detailed asteroseismic modeling will be able to<br>\nmeet the PLATO standards for such a solar-like star.</p>",
