cds-question@unistra.frg-starsstellar-atmospheresAn analysis of data on chromospheric activity obtained in the framework of exoplanet-search programs is presented. Observations of 1334 stars showing that the chromospheric activity of the Sun is clearly higher than for the vast majority of stars in the solar vicinity are used. A comparison of chromospheric and coronal activity led to the identification of a significant group of stars with a low level of chromospheric activity, whose coronal radiation spans wide ranges.2011AZh....88.1217Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/88/1217CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/88/1217https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/88/1217http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/88/1217https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/88/1217https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/88/1217http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/88/1217GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AZh/88/1217/table (Data on stars with specified indices of chromospheric and coronal activity)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AZh/88/1217/table?https://vizier.iucaa.in/viz-bin/conesearch/J/AZh/88/1217/table?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AZh/88/1217/table?GETtext/xml+votable180.050000true5.5983489-27.03257420.0055555555555555566/137 309 535 679 684 748 815 871 1341 1597 2110 2254 2317 2472 3020 3095 3102 3979 4136 4839 5009 5074 5522 5718 6066 6760 6766 6791 6831 7240 7746 7763 8094 8224 8342 8357 8466 8476 8790 8843 8896 8995 9179 9403 9492 9801 9843 10045 10375 10899 12146 12465 12644 12899 12944 12983 13301 13547 14412 14419 14426 14525 14546 14548 14650 15174 16069 16508 16652 16689 16792 17137 17219 17425 17453 17721 17730 17847 18139 18614 18821 19904 19912 20145 20701 20753 21177 21185 21484 21726 21838 21906 22252 22654 22708 22818 22878 23140 23177 23201 23369 23826 24019 24178 24713 25407 26183 26242 26575 26975 26978 27018 27616 27712 27750 27973 28122 28130 28180 28605 28664 28763 28987 29136 29196 29327 29513 29541 30015 30526 30529 30576 30965 31101 31130 31132 31425 31433 31478 31860 32549 32561 32619 32645 32757 35802 36246 36365 36379 36697 38545 39562 39646 40078 40442 40692 40823 43813 43911 43989 44243 44398 44891 46967 48105 49114https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AZh/88/1217?format=asciiOpticaldefaultJ/AZh/88/1217/tableData on stars with specified indices of chromospheric and coronal activityrecnoRecord number assigned by the VizieR team.
