cds-question@unistra.frmultiple-starssolar-system-planetsphotometryMotivated by the previously reported high orbital decay rate of the planet WASP-43b, we have obtained and present eight newly transiting light curves. Together with other data in the literature, we perform a self-consistent timing analysis with data covering a timescale of 1849 epochs. The results give an orbital decay rate dP/dt=-0.02890795+/-0.00772547s/year, which is one order smaller than previous values. This slow decay rate corresponds to a normally assumed theoretical value of the stellar tidal dissipation factor. In addition, through the frequency analysis, the transit timing variations presented here are unlikely to be periodic, but could be signals of a slow orbital decay.2016AJ....151...17Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/151/17CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/PASP/127/143 : WASP-39b and WASP-43b light curves (Ricci+, 2015)J/A+A/563/A41 : WASP-43 OSIRIS transmission spectroscopy (Murgas+, 2014)J/A+A/563/A40 : WASP-43b g'r'i'z'JHK light curves (Chen+, 2014)J/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/AJ/151/17https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/151/17http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/151/17https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/151/17https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/151/17http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/151/17GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/151/17/table1The log of observations of this workDateUT datetime.epochnullableFlt[R] Filtermeta.id;instr.filtercharrecnoRecord number assigned by the VizieR team.
