cds-question@unistra.frmultiple-starssolar-system-planetschemical-abundancesPrecise stellar parameters are crucial in exoplanet research for correctly determining of the planetary parameters. For stars hosting a transiting planet, determining of the planetary mass and radius depends on the stellar mass and radius, which in turn depend on the atmospheric stellar parameters. Different methods can provide different results, which leads to different planet characteristics. In this paper, we use a uniform method to spectroscopically derive stellar atmospheric parameters, chemical abundances, stellar masses, and stellar radii for a sample of 90 transit hosts. Surface gravities are also derived photometrically using the stellar density as derived from the light curve. We study the effect of using these different surface gravities on the determination of the chemical abundances and the stellar mass and radius. A spectroscopic analysis based on Kurucz models in LTE was performed through the MOOG code to derive the atmospheric parameters and the chemical abundances. The photometric surface gravity was determined through isochrone fitting and the use of the stellar density, directly determined from the light curve. Stellar masses and radii are determined through calibration formulae. Spectroscopic and photometric surface gravities differ, but this has very little effect on the precise determination of the stellar mass in our spectroscopic analysis. The stellar radius, and hence the planetary radius, is most affected by the surface gravity discrepancies. For the chemical abundances, the difference is, as expected, only noticable for the abundances derived from analyzing of lines of ionized species.2013A&A...558A.106Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/558/A106CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/543/A45 : Planets around metal-poor stars (Mortier+, 2012)J/A+A/551/A112 : Metallicity-giant planet correlation (Mortier+, 2013)J/A+A/557/A70 : Evolved planet hosts - stellar parameters (Mortier+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/558/A106https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/558/A106http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/558/A106https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/558/A106https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/558/A106http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/558/A106GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/558/A106/stars (Stellar parameters and abundances for the transit hosts studied)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/558/A106/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/558/A106/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/558/A106/stars?GETtext/xml+votable180.050000true102.0798833-3.10213330.0055555555555555566/876 3876 4990 6181 6638 7240 8197 8237 9173 9355 9459 12424 12644 12983 13143 13439 13569 13680 13702 14816 14825 14914 14918 14973 15129 15143 16405 16432 16947 17172 17819 18093 18569 18766 20116 20339 21989 22001 22065 22078 22120 22208 22816 24409 25132 25194 25604 26019 26062 28400 28433 28821-28822 30295 30450 30466 31641 32749 33798 34708 35210 36142 36165 36667 36794 37246-37247 37329 37923 38452 38682 39487 39611 40862 42936 43625 43775 43847 43960 44648 46421 46429 46437 47476 48803https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/558/A106?format=asciidefaultJ/A+A/558/A106/starsStellar parameters and abundances for the transit hosts studiedrecnoRecord number assigned by the VizieR team.
