cds-question@unistra.frmultiple-starssolar-system-planetsphotometryradial-velocityXO-2 is the first confirmed wide stellar binary system where the almost twin components XO-2N and XO-2S have planets, and it is a peculiar laboratory in which to investigate the diversity of planetary systems. This stimulated a detailed characterization study of the stellar and planetary components based on new observations. We collected high-resolution spectra with the HARPS-N spectrograph and multi-band light curves. Spectral analysis led to an accurate determination of the stellar atmospheric parameters and characterization of the stellar activity, and high-precision radial velocities of XO-2N were measured. We collected 14 transit light curves of XO-2Nb used to improve the transit parameters. Photometry provided accurate magnitude differences between the stars and a measure of their rotation periods.2015A&A...575A.111Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/575/A111CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/527/A85 : Light curves of HAT-P-3b and HAT-P-14b (Nascimbeni+, 2011)J/A+A/554/A28 : Qatar-1 differential light curve (Covino+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/575/A111https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/575/A111http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/575/A111https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/575/A111https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/575/A111http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/575/A111GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/575/A111/xo2ntraTransit light curves of XO-2N collected in R-band, in the framework of the TASTE project, with the facilities described in Table 4 (Fig.8 of paper)recnoRecord number assigned by the VizieR team.
