cds-question@unistra.frasteroseismologydwarf-starssubdwarf-starsg-starsThe Transiting Exoplanet Survey Satellite (TESS) is conducting a nearly full-sky survey, enabling the photometric characterisation of millions of stars. The forthcoming PLAnetary Transits and Oscillations of stars mission (PLATO) will provide long-duration, high-precision photometry of tens of thousands of bright stars to be characterised through asteroseismology. The TESS Luminaries Sample is a catalogue of 196 bright naked-eye (V<6) main-sequence (MS) and sub-giant (SG) stars exhibiting solar-like oscillations. Among them, the subset located within the PLATO Long-duration Observation Phase (LOP) fields constitutes an exceptional set of targets that will be observable by PLATO from the earliest phases of the mission, making them ideal calibrators during commissioning and the first months of science operations. This paper aims to provide an in-depth asteroseismic characterisation of 32 Luminaries stars that fall within the PLATO LOP fields of view. Individual mode parameters were extracted using three independent seismic pipelines, one of which was similar to the algorithms used in the official PLATO pipeline. The Peirce criterion and a Z-score were applied to identify the optimal combination of data calibration, observing cadence, and fitting pipeline for each star. We analyse 32 MS and SG stars up to TESS Sector 88, with individual mode frequencies derived for the first time for 26 of them. For all stars, we derived large and small separations, the asymptotic phase term epsilon, radial mode amplitudes, and mean linewidths per order. Comparisons with previous Kepler observations reveal consistent trends in the seismic parameters, confirming the robustness of our analysis based on TESS data. In sub-giants, mixed-mode identification differs in the three pipelines, revealing extraction inconsistencies requiring longer datasets to improve our mode identifications. These results demonstrate the capability of TESS to deliver high-quality asteroseismic observations for MS and SG stars. The Luminaries stars located in the PLATO LOP fields constitute a unique sample that will play a crucial role in validating, calibrating, and optimising PLATO's seismic performance from the earliest stages of the mission.2026A&A...712A..33Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/712/A33CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/701/A285 : TESS Luminaries Sample.
