cds-question@unistra.freclipsing-binary-starssolar-system-planetsphotometryWe present VLT eclipse photometry for the giant planet CoRoT-1b. We observed a transit in the R-band filter and an occultation in a narrow filter centered on 2.09{mu}m. Our analysis of this new photometry and published radial velocities, in combination with stellar-evolutionary modeling, leads to a planetary mass and radius of 1.07^+0.13^_-0.18_M_{Jup}_ and 1.45^+0.07^_-0.13_R_{Jup}, confirming the very low density previously deduced from CoRoT photometry. The large occultation depth that we measure at 2.09{mu}m (0.278^0.043^_-0.066_% ) is consistent with thermal emission and is better reproduced by an atmospheric model with no redistribution of the absorbed stellar flux to the night side of the planet.2009A&A...506..359Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/506/359CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/corot : CoRoT observation log (CoRoT, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/506/359https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/506/359http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/506/359https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/506/359https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/506/359http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/506/359GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/506/359/fors-r*103 measurements obtained with VLT/FORS2 R_SPECIAL filter ({lambda}_eff_=655nm, FWHM=165nm) on 2008 February 28recnoRecord number assigned by the VizieR team.
