cds-question@unistra.frdwarf-starsvariable-starsmagnetic-fieldsasteroseismologyvisible-astronomyWe present a new catalog of stars for which detected solar-like oscillations and magnetic activity measurements from chromospheric spectroscopic observations are both available. Our results were obtained by exploiting NASA TESS mission light curves for active stars observed within the Mount Wilson Observatory HK project and the HK survey of the Hamburg Robotic Telescope TIGRE. We analyzed the light curves for a total of 191 stars by adopting recent techniques based on Bayesian analysis and model comparison to assess the detection of a power excess originating from solar-like oscillations. We characterized the oscillations in a total of 34 targets, for which we provide estimates for the global asteroseismic parameters of {nu}_max_ (the frequency of maximum oscillation power), {DELTA}{nu} (the large frequency separation), and for the amplitude of the solar-like oscillation envelope Amax. We provide strong statistical evidence for the detection of solar-like oscillations in 15 stars of our sample, identify six further stars where a detection is likely, and 13 stars for which oscillations cannot be ruled out. The key parameters extracted in this work will be exploited for a detailed stellar modeling of the targets and to calibrate relations that connect the level of the measured magnetic activity to the suppression induced on the global oscillation amplitudes. This opens the possibility of shedding light on the interplay between magnetic fields and oscillations. Because of their relatively high brightness, the targets may also be of interest for future dedicated follow-up observations using both photometry and spectropolarimetry.2024A&A...683A.161Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/683/A161CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/683/A161https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/683/A161http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/683/A161https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/683/A161https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/683/A161http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/683/A161GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/683/A161/table1 (Stars with firm detection)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/683/A161/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/683/A161/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/683/A161/table1?GETtext/xml+votable180.050000true10.1366417-23.80492470.005555555555555556Cone search capability for table J/A+A/683/A161/table2 (Stars with likely or possible detection)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/683/A161/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/683/A161/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/683/A161/table2?GETtext/xml+votable180.050000true23.4284822-7.02534420.0055555555555555566/2490 3020 3390 4468 5013 5522 5676 6183 8843 8845 9835 10375 12592 15865 16679 17137 17606 17812 18139 19547 22654 23369 24160 26575 26778 30529 30576 32552 36693 36697 40408 40690 40823 43804https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/683/A161?format=asciiOpticaldefaultJ/A+A/683/A161/table1Stars with firm detectionrecnoRecord number assigned by the VizieR team.
