cds-question@unistra.frmultiple-starssolar-system-planetsspectroscopyWe used the Gran Telescopio Canarias (GTC) instrument OSIRIS to obtain long-slit spectra in the optical range 520-1040nm of the planetary host star WASP-43 and of a reference star during a full primary transit event. We integrated the stellar flux of both stars in different wavelength regions producing several light curves. We measure a mean planet-to-star radius ratio in the white light curve of 0.15988^+0.00133^_-0.00145_. We present a tentative detection in the planet-to-star radius ratio around the NaI doublet ({lambda} 588.9, 589.5nm) when compared to the nearby continuum at the 2.9-sigma level. We find no significant excess of the measured planet-to-star radius ratio around the KI doublet ({lambda} 766.5nm, 769.9nm) when compared to the nearby continuum.2014A&A...563A..41Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/563/A41CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/542/A4 : WASP-43b thirty eclipses (Gillon+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/563/A41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/563/A41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/563/A41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/563/A41https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/563/A41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/563/A41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/563/A41/table1White light curverecnoRecord number assigned by the VizieR team.
