cds-question@unistra.frmultiple-starssolar-system-planetsradial-velocityWe present Rossiter-McLaughlin observations of the transiting super-Earth 55 Cnc e collected during six transit events between 2012 January and 2013 November with HARPS and HARPS-N. We detect no radial velocity signal above 35 cm/s (3{sigma}) and confine the stellar vsini_*_ to 0.2+/-0.5 km/s. The star appears to be a very slow rotator, producing a very low amplitude Rossiter-McLaughlin effect. Given such a low amplitude, the Rossiter-McLaughlin effect of 55 Cnc e is undetected in our data, and any spin-orbit angle of the system remains possible. We also performed Doppler tomography and reach a similar conclusion. Our results offer a glimpse of the capacity of future instrumentation to study low amplitude Rossiter-McLaughlin effects produced by super-Earths.2014ApJ...792L..31Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/792/L31CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/533/A114 : Transit of super-Earth 55 Cnc e (Demory+, 2011)J/A+A/539/A28 : New transit photometry for super-Earth 55 Cnc ehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/792/L31https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/792/L31http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/792/L31https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/792/L31https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/792/L31http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/792/L31GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/792/L31/table1Radial velocities of all spectra of 55 Cnc observed with HARPS and HARPS-NrecnoRecord number assigned by the VizieR team.
