cds-question@unistra.frsupernovaegalaxiescatalogssurveysUsing a sample of nearby spiral galaxies hosting 185 supernovae (SNe) Ia, we perform a comparative analysis of the locations and light-curve decline rates ({Delta}m_15_) of normal and peculiar SNe Ia in the star formation deserts (SFDs) and beyond. To accomplish this, we present a simple visual classification approach based on the UV/H {alpha} images of the discs of host galaxies. We demonstrate that, from the perspective of the dynamical time-scale of the SFD, where the star formation is suppressed by the bar evolution, the {Delta}m_15_ of SN Ia and progenitor age can be related. The SFD phenomenon gives an excellent possibility to separate a subpopulation of SN Ia progenitors with ages older than a few Gyr. We show, for the first time, that the SFDs contain mostly faster declining SNe Ia ({Delta}m_15_>1.25). For the galaxies without SFDs, the region within the bar radius, and outer disc contain mostly slower declining SNe Ia. To better constrain the delay times of SNe Ia, we encourage new studies (e.g. integral field observations) using the SFD phenomenon on larger and more robust datasets of SNe Ia and their host galaxies.2021MNRAS.505L..52Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/505/L52CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/499/1424 : Properties of 407 SNe and their 394 hosts (Hakobyan+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/505/L52https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/505/L52http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/505/L52https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/505/L52https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/505/L52http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/505/L52GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/505/L52/tablea1 (Properties of 185 SNe and their 180 hosts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/505/L52/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/505/L52/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/505/L52/tablea1?GETtext/xml+votable180.050000true186.612916731.22333330.0055555555555555566/34 611 626 697 928 1796 2142 2251 2353 2391 2641 3393 4401 4416 4583 4719 5004 5006 5095 5100 5192 5639 5975 6062 6101 6178 6549 6936 7044 7104 7241 7369 7659 7679 7783 8064 8169 8927 9449 9614 9698 9794 10232 10397 10428 10563 10734 10789 10817 10858 11064 11280 11434 11939 12455 12497 12620 13350 13399 13505 13529 13545 14882 15197 15548 15954-15955 16612 16690 16852 17197 17278 17410 17500 17741 17817 18081 18206 18296 18394 18735 19051 19227 19241 19515 19554 19581 20014 20090 20140 20237 20279 20283 20318 20370 20601 21584 21857 22826 22963 23013 23023 23077 23157 23828 24131 24152 24716 24926 24969 25078-25079 25141 25333 25491 25513 25715 25769-25770 25889 26271 26336 26392 26563 27348 27367 27512 27634 27761 27918 27945 28035 28040 28112 28167 28299 28353 28509 28529 28579 30044 30160 31293 31628 31881 32129 32307 32561 32569 32602 33228 33681 34531 35844 36131 36287 36919 37299 37429 37580 38664 38956 39627 39836 40337 43245 43339 43855 44359 44660 44896 45041 45418 46104 46882 47064 48075 48665https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/505/L52?format=asciidefaultJ/MNRAS/505/L52/tablea1Properties of 185 SNe and their 180 hostsSimbadNameSimbad column added by the CDSmeta.idcharnullableSNlocSN locationmeta.codecharrecnoRecord number assigned by the VizieR team.
