cds-question@unistra.frsupernovaeredshiftedWe study the stellar populations of Type Ia supernova (SN Ia) host galaxies using Sloan Digital Sky Survey (SDSS)-II spectroscopy. The main focus is on the relationships of SN Ia properties with stellar velocity dispersion and the stellar population parameters age, metallicity and element abundance ratios. We concentrate on a sub-sample of 84 SNe Ia from the SDSS-II Supernova Survey and find that SALT2 stretch factor values show the strongest dependence on stellar population age. Hence, more luminous SNe Ia appear in younger stellar progenitor systems. No statistically significant trends in the Hubble residual with any of the stellar population parameters studied are found. Moreover, the method of photometric stellar mass derivation affects the Hubble residual-mass relationship. For an extended sample (247 objects), including SNe Ia with SDSS host galaxy photometry only, the Hubble residual-mass relationship behaves as a sloped step function. In the high-mass regime, probed by our host spectroscopy sample, this relationship is flat. Below a stellar mass of ~2x10^10^M_{sun}_, i.e. close to the evolutionary transition mass of low-redshift galaxies, the trend changes dramatically such that lower mass galaxies possess lower luminosity SNe Ia after light-curve corrections. The sloped step function of the Hubble residual-mass relationship should be accounted for when using stellar mass as a further parameter for minimizing the Hubble residuals.2013MNRAS.435.1680Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/435/1680CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/135/348 : SDSS-II SNe survey: search and follow-up (Sako+, 2008)J/AJ/135/1766 : Sloan Digital Sky Survey-II supernova survey (Zheng+, 2008)J/AJ/136/2306 : SDSS-II Supernova survey, 2005 (Holtzman+, 2008)J/ApJS/185/32 : First-year SDSS-II SN results (Kessler+, 2009)J/ApJ/708/661 : SDSS-II SN Survey: SNe II-P standardization (D'Andrea+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/435/1680https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/435/1680http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/435/1680https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/435/1680https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/435/1680http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/435/1680GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/435/1680/appen (Properties of the SNIa host galaxies studied)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/435/1680/appen?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/435/1680/appen?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/435/1680/appen?GETtext/xml+votable180.050000true329.73-0.4990.0055555555555555565/4502 4518 4521 6/0-2 17406-17407 17662-17663 17725 17745 17747 17749-17754 17756 17761-17762 17766 17772 17774 17776 17778 17806 17809-17810 17813-17816 17818-17819 17821-17822 17825 17827 17829 17831-17833 17840 17843 17856-17857 17981 17983 17999 18001 18005-18006 18013-18014 18017 18020-18022 18026-18028 18032-18034 18062-18063 18065-18067 18071 18076 18078 18082-18083 18090 18092-18093 18096-18097 18766 18769 18771-18774 18780 18782 18787-18789 18792-18794 18796-18797 18802 18835-18837 18840-18841 18849-18851 18853-18854 18856 18858-18859 18862 18882 19005 19007 19022-19023 19027 19029 19035-19036 19041 19043 19046-19049 19051 19054 19087 19089 19091 19093-19094 19097 19101-19102 19108-19109 19115 19122 19136 19200 19457-19458 23102-23103 23144 23146 23183 23186 23189-23193 23195-23197 23201 23203-23206 23208-23209 23211 23213-23214 23216 23218 23232 30031 30033 30036 30038 30042 30053 30064-30065 36860-36861 36863 49149 49151https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/435/1680?format=asciiOpticaldefaultJ/MNRAS/435/1680/appenProperties of the SNIa host galaxies studiedrecnoRecord number assigned by the VizieR team.
