cds-question@unistra.fropen-star-clustersx-ray-sourcespre-main-sequence-starsSeveral studies showed that the magnetic activity of late-type main-sequence (MS) stars is characterized by different regimes and that their activity levels are well described by the Ross by number, Ro, defined as the ratio between the rotational period P_rot_ and the convective turnover time. Very young pre-main-sequence (PMS) stars show, similarly to MS stars, intense magnetic activity. However, they do not show clear activity-rotation trends, and it still debated which stellar parameters determine their magnetic activity levels. To bridge the gap between MS and PMS stars, we studied the activity-rotation relation in the young cluster h Persei, a ~13Myr old cluster, that contains both fast and slow rotators. The cluster members have ended their accretion phase and have developed a radiative core. It therefore offers us the opportunity of studying the activity level of intermediate-age PMS stars with different rotational velocities, excluding any interactions with the circumstellar environment We constrained the magnetic activity levels of h Per members by measuring their X-ray emission from a Chandra observation, while rotational periods were obtained previously in the framework of the MONITOR project. By cross-correlating these data, we collected a final catalog of 414 h Per members with known rotational period, effective temperature, and mass. In 169 of these, X-ray emission has also been detected.2016A&A...589A.113Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/589/A113CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/122/248 : h and chi Per UBVI,H{alpha} photometry (Keller+, 2001)J/A+A/394/479 : uvby{beta} photometry of h and chi Per (Capilla+, 2002)J/ApJ/576/880 : CCD UBV photometry of h and {chi} Per (Slesnick+, 2002)J/PASP/114/233 : h and {chi} Per memberships (Uribe+, 2002)J/ApJ/669/L33 : H{alpha} emission sources in h and {chi} Per (Currie+, 2007)J/A+A/560/A13 : Stellar rotation in h Per (Moraux+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/589/A113https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/589/A113http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/589/A113https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/589/A113https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/589/A113http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/589/A113GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/589/A113/table1 (X-ray source detected in the CHANDRA/ACIS-I observations of h Per)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/589/A113/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/589/A113/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/589/A113/table1?GETtext/xml+votable180.050000true34.464416757.16719440.0055555555555555566/3256 32582.367228618189496e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/589/A113?format=asciiX-raydefaultJ/A+A/589/A113/table1X-ray source detected in the CHANDRA/ACIS-I observations of h PerrecnoRecord number assigned by the VizieR team.
