cds-question@unistra.frasteroseismologydwarf-starsg-starsspectroscopic-binary-starsexoplanetsvisible-astronomyWe aim to detect and characterise solar-like oscillations in bright naked-eye (V<6) main-sequence and subgiant stars observed by the Transiting Exoplanet Survey Satellite (TESS). In doing so, we seek to expand the current benchmark sample of oscillators, provide accurate global asteroseismic parameters for these bright targets, and assess their potential for future detailed investigations -- including missions such as the Habitable Worlds Observatory (HWO) and PLAnetary Transits and Oscillations of stars (PLATO). Our sample of bright stars was selected from the Hipparcos/Tycho catalogues. We analysed TESS photometry from both 120-s and 20-s cadences using the standard TESS Science Processing Operations Center (SPOC) light curves and custom apertures extracted from target pixel files. After applying a filtering of the light curves, we extracted global asteroseismic parameters ({nu}_max_ and {Delta}{nu}) using the pySYD pipeline. Results were cross-validated with independent pipelines and compared to predictions from the Asteroseismic Target List (ATL), while noise properties were evaluated to quantify improvements from a 20-s observing cadence. We detect solar-like oscillations in a total of 196 stars -- including 128 new detections -- with extracted {nu}_max_ and {Delta}{nu} values showing strong conformity to expected scaling relations. This corresponds to an increase by more than an order of magnitude in the number of main-sequence stars with detection of solar-like oscillations from TESS. Importantly, our sample of newly detected solar-like oscillators includes nearly 40% of the prime targets for HWO, paving the way for a systematic determination of asteroseismic ages that will be important for the possible interpretation of atmospheric biosignatures. Our analysis confirms that 20-s cadence data yields lower high-frequency noise levels compared to 120-s data. Moreover, the precise stellar parameters obtained through asteroseismology establish these bright stars as benchmarks for seismic investigations and provide useful constraints for refining stellar evolution models and for complementary analyses in interferometry, spectroscopy, and exoplanet characterisation.2025A&A...701A.285Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/701/A285CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/701/A285https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/701/A285http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/701/A285https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/701/A285https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/701/A285http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/701/A285GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/701/A285/tabled1 (table)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/701/A285/tabled1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/701/A285/tabled1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/701/A285/tabled1?GETtext/xml+votable180.050000true208.718.40.005555555555555556Cone search capability for table J/A+A/701/A285/tabled2 (PLATO table)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/701/A285/tabled2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/701/A285/tabled2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/701/A285/tabled2?GETtext/xml+votable180.050000true122.253-61.3020.005555555555555556Cone search capability for table J/A+A/701/A285/tabled4 (Interferometry table)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/701/A285/tabled4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/701/A285/tabled4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/701/A285/tabled4?GETtext/xml+votable180.050000true208.718.40.005555555555555556Cone search capability for table J/A+A/701/A285/tabled6 (Missing)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/701/A285/tabled6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/701/A285/tabled6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/701/A285/tabled6?GETtext/xml+votable180.050000true263.712.60.0055555555555555566/62 706 748 934 1247 1341 2169 2472 2476 2650 2691 2822 3020 3036 3102 3118 3314 3932 4438 4808 4854 5154 5484 5522 5718 5836 6066 6107 6308 6926 6941 7238 7390 7595 7958 8109 8477 8716 8845 8935 9327 9403 9476 9835 10225 10899 11314 11403 11534 11617 11620 11636 11638 11691 11732 11773 12120 12238 12464 12798 13440 13474 14146 14419 14459 14522 14630 14845 15170 15172 15174 15177 15249 15356 15562 15620 15944 15962 15984 16069 16105 16192 16412 17137 17171 17606 17847 17860 17918 18002 19237 19312 19323 19417 19585 19733 20145 20656 21060 21179 21240 21696 22120 22157 22180 22330 22654 22708 22823 22878 23076 23190 23201 23675 23820 24028 24209 24721 24743 24924 24951 25231 25407 25473 25686 25869 25919 26575 26975 27268 28866 28915 28987 29021 29086 29089 29136 29155 29183 29196 29212 29225 29239 29255 29327 29347 29454 29630 29633 29680 29712-29713 30269 30419 30458 30529 30576 30664 30798 30804 30859 30872 30878 30897 30914 30965 30995 31061 31073 31078 31132 31149 31325 31399 31478 31561 31614 31619 31751 31760 31763 31776 31789 31830 31849 31929 32192 32288 32291 32357 32552 32619 32645 32848 32875 33184 33211 33281 33447 33910 34096 34446 34817 34864 35064 35362 35948 35968 35994 36035 36145 36379 36564 36693 37022 37214 37408 37585 37595 38048 38064 38238 39096 39305 39490 39500 39709 39926 40242 40716 40823 41272 41750 41941 42249 42253 42486 42903 43074 43093 43577 43595 43639 44284 44411 44435 44494 44651 44737 44833 44844 44879 45143 45353 45485 45535 45669 45865 46022 46529 46982 47137 47997 48122 48354 48531 48546 48552 48589 48591 48606 48613 48709 48749 48910 48933 48963 48986 49047 49060https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/701/A285?format=asciiOpticaldefaultJ/A+A/701/A285/tabled1tablerecnoRecord number assigned by the VizieR team.
