cds-question@unistra.frvariable-starsspectroscopyWe present the CoRoT light curve of the bright B2.5V star HD 48977 observed during a short run of the mission in 2008, as well as a high-resolution spectrum gathered with the HERMES spectrograph at the Mercator telescope. We use several time series analysis tools to explore the nature of the variations in the light curve. We performed a detailed analysis of the spectrum of the star to determine its fundamental parameters and its element abundances. We find a large number of high-order g-modes, and one rotationally induced frequency. We find stable low-amplitude frequencies in the p-mode regime as well.2013A&A...551A..12Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/551/A12CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/506/111 : Frequency analysis of HD 180642 (V1449 Aql) (Degroote+, 2009)J/A+A/506/471 : Frequency analysis of CoRoT B stars (Degroote+, 2009)J/A+A/525/A23 : Frequency analysis of HD 49434 (Mathias+, 2011)J/A+A/544/A106 : p-mode frequencies of the solar twin 18 Sco (Bazot+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/551/A12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/551/A12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/551/A12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/551/A12https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/551/A12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/551/A12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/551/A12/table1Frequencies in the light curve of HD 48977recnoRecord number assigned by the VizieR team.
