cds-question@unistra.frmagnetic-fieldseffective-temperatureStarspots are created by local magnetic fields on the surfaces of stars, just as sunspots. Their fields are strong enough to suppress the overturning convective motion and thus block or redirect the flow of energy from the stellar interior outwards to the surface and consequently appear as locally cool and therefore dark regions against an otherwise bright photosphere. This article is an attempt to review our current knowledge of starspots.2009A&ARv..17..251Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/A+ARV/17.251CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.aip.de/groups/activity/ : AIP Stellar Activity Grouphttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/A+ARV/17.251https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/A+ARV/17.251http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/A+ARV/17.251https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/A+ARV/17.251https://vizier.iucaa.in/viz-bin/votable?-source=J/other/A+ARV/17.251http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/A+ARV/17.251GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/A+ARV/17.251/table1 (Late-type stars with Doppler images (as of 2008))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/A+ARV/17.251/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/A+ARV/17.251/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/A+ARV/17.251/table1?GETtext/xml+votable180.050000true75.03424893.2866750.0055555555555555566/311 463 473 496 845 1050 1074 1115 1168-1169 1171 2339 3091 3100 3136 3138 6122 6241 6340 7925 8124 8843 9442 10255 11856 12770 13110 13451 14020 14035 15267 15368 17124 19930 20102 20205 20286 20327 21501 22680 22707 22805 23010 23191 24862 25452 25851 28126 30029 31774 32147 33034 33116 33287 33966 35025 37231 37790 38800 40131 40321 40784 41295 41973 42684 42736 42981 43087 44894 47287 48163https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/A+ARV/17.251?format=asciidefaultJ/other/A+ARV/17.251/table1Late-type stars with Doppler images (as of 2008)NameStar namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
