cds-question@unistra.frdwarf-starsUsing two different spectrographs, High Accuracy Radial velocity Planet Search (HARPS) (European Southern Observatory) and SOPHIE (Observatoire de Haute Provence), we have measured vsini for a sample of dK5 stars. These are the first measurements of vsini for most of the stars studied here. We measured vsini to an accuracy of 0.3km/s and a detection limit of about 0.5-1km/s. All our targets have similar (R-I)c colour. This is an advantage and facilitates the determination of the narrowest line profiles for vsini~0. In our total sample, we detected rotation for 22 stars (three dK5e and 19 dK5 stars), and we did not detect rotation in a further 22 stars. This result shows that there are many dK5 slow rotators, and many more than for dM1 stars. We also report on a newly discovered dK5e star, McC 522, which is also the fastest rotator in our sample.2011MNRAS.416.2233Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/416/2233CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/403/2157 : Main-sequence star chromospheres (Houdebine+, 2010)J/MNRAS/407/1657 : Rotation velocities of dwarf M stars (Houdebine, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/416/2233https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/416/2233http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/416/2233https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/416/2233https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/416/2233http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/416/2233GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/416/2233/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/416/2233/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/416/2233/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/416/2233/stars?GETtext/xml+votable180.050000true163.61041776.0658330.0055555555555555566/181 237 601 650 1025 2572 3004 3638 3786 4118 4866 5371 5773 5824 6405 6752 7129 7443 7989 8016 8132 8790 8887 8946 8979 9449 9776 10431 11053 11732 12026 12340 12446 12494 12540 13301 14339 15243 15775 16300 16355 16657 17017 17777 19097 19626 19816 19836 21971 22813 23450 24212 25316 25342 25793 26016 27109 27217 27335 27725 27846 27954 28205 28571 28596 29196 30176 30343 31011 31545 31998 32001 32224 33442 36049 36174 37592 38461 39500 44284 45021 45391 46925 47201 47758https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/416/2233?format=asciiOpticaldefaultJ/MNRAS/416/2233/starsList of studied starsrecnoRecord number assigned by the VizieR team.
