cds-question@unistra.frsupernovaeline-intensitiesspectroscopyWe present an investigation of the optical spectra of 264 low-redshift (z<0.2) Type Ia supernovae (SNe Ia) discovered by the Palomar Transient Factory, an untargeted transient survey. We focus on velocity and pseudo-equivalent width measurements of the SiII 4130, 5972, and 6355{AA} lines, as well those of the CaII near-infrared (NIR) triplet, up to +5days relative to the SN B-band maximum light. We find that a high-velocity component of the CaII NIR triplet is needed to explain the spectrum in ~95% of SNe Ia observed before -5days, decreasing to ~80% at maximum. The average velocity of the CaII high-velocity component is ~8500km/s higher than the photospheric component. We confirm previous results that SNe Ia around maximum light with a larger contribution from the high-velocity component relative to the photospheric component in their CaII NIR feature have, on average, broader light curves and lower CaII NIR photospheric velocities. We find that these relations are driven by both a stronger high-velocity component and a weaker contribution from the photospheric CaII NIR component in broader light curve SNe Ia. We identify the presence of CII in very-early-time SN Ia spectra (before -10days), finding that >40% of SNe Ia observed at these phases show signs of unburnt material in their spectra, and that CII features are more likely to be found in SNe Ia having narrower light curves.2014MNRAS.444.3258Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/444/3258CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/313 : PTF photometric catalog 1.0 (Ofek+, 2012)J/AJ/142/60 : Palomar Transient Factory Orion Project (Van Eyken+, 2011)J/ApJ/736/159 : Photometry monitoring of the SN PTF10vdl (Gal-Yam+, 2011)J/MNRAS/438/1391 : Host galaxies of Type Ia SN from PTF (Pan+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/444/3258https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/444/3258http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/444/3258https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/444/3258https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/444/3258http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/444/3258GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/444/3258/SNe (Light-curve information, heliocentric redshift and spectral measurement information for each SN Ia in the sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/444/3258/SNe?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/444/3258/SNe?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/444/3258/SNe?GETtext/xml+votable180.050000true215.982583335.18477780.0055555555555555566/68 191 560 611 719 732 740 2089 2111 2156 2188 2254 2263 2509 2564 4556 4577 4685 4806 5067 5130 5238 5751 5928 6014 6263 6606 6625 6962 7197 7241-7242 7662 7784 8276 8282 8300 8304 8329 8419 8486 8543 8566 8571 8661 9053 9219 9260 9311 9329 9331 9333 9338 9351 9369 9434 9439 9462 9471 9501 9510 9531 9533 9571 9591 9604 9619 9631 9657 9723 9876 9878 9880 9889 9914 9950 9958 9967 9999 10002 10038 10079 10110 10114 10118 10135 10149 10152 10214 10218 10261 10377 10379 10403 10434 10442 10468 10473 10493 10496 10509 10521 10534 10597 10635 10637 10641 10672-10673 10747 10825 10838-10839 10844-10846 10921 10963 10980 10984 11044 11071 11100 11103-11104 11167 11215 11218 11255 11285 11287 11294 11300 11345 11419 11427 11430 11434 11473 11499 11615 11625 11630 11648 11653 11803 11880 12035 12209 12371 12379-12380 12567 12610 13452 13521 13572 13576 13601 16542 16653 17174 17237 17239 17522 17525 17533 17671 17782 17829 17834 18000 18011 18109 18238 18538 18682 18854 18880 18916 18933 19187 19244 19344 19362 19394 19450 19522 19624 19681 19688 19692 19846 19851 19860 19866 19870 19941 19970 19991-19992 20058 20109 20126 20213 20291 20364 20382 21151 23075 23084 25175 25634 26089 26094 26117 26261 26304 26330 26339 26341 26351 26452 26563 26803 27256 27347 27738-27739 27743 27749 27757 27764 27772 27859 27929 27942 27950 27966 28012 28026 28068 28080 28182 28455 28468 31631 31685 32404 32413 32505 32509 32681 44028 49023 49115 49132https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/444/3258?format=asciiOpticaldefaultJ/MNRAS/444/3258/SNeLight-curve information, heliocentric redshift and spectral measurement information for each SN Ia in the samplerecnoRecord number assigned by the VizieR team.
