cds-question@unistra.frsupernovaegalaxiesvisible-astronomycatalogssurveysWe present an analysis of the light curve (LC) decline rates ({DELTA}m_15_) of 407 normal and peculiar supernovae (SNe) Ia and global parameters of their host galaxies. As previously known, there is a significant correlation between the {DELTA}m_15_ of normal SNe Ia and global ages (morphologies, colours, and masses) of their hosts. On average, those normal SNe Ia that are in galaxies from the Red Sequence (early-type, massive, old hosts) have faster declining LCs in comparison with those from the Blue Cloud (late-type, less massive, younger hosts) of the colour-mass diagram. The observed correlations between the {DELTA}m_15_ of normal SNe Ia and hosts' parameters appear to be due to the superposition of at least two distinct populations of faster and slower declining normal SNe Ia from older and younger stellar components. We show, for the first time, that the {DELTA}m_15_ of 91bg- and 91T-like SNe is independent of host morphology and colour. The distribution of hosts on the colour-mass diagram confirms the known tendency for 91bg-like SNe to occur in globally red/old galaxies, while 91T-like events prefer blue/younger hosts. On average, the youngest global ages of 02cx-like SNe hosts and their positions in the colour-mass diagram hint that these events likely originate from young population, but they differ from 91T-like events in the LC decline rate. Finally, we discuss the possible explosion channels and present our favoured SN Ia models that have the potential to explain the observed SN-host relations.2020MNRAS.499.1424Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/499/1424CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)J/A+A/544/A81 : Supernovae and their hosts in SDSS DR8 (Hakobyan+, 2012)J/MNRAS/444/2428 : Disturbance levels of SNe host galaxies (Hakobyan+, 2014)J/MNRAS/456/2848 : Properties of 500 SNe & their 419 hosts (Hakobyan+, 2016)J/MNRAS/471/1390 : Properties of 102 SNe & their 100 hosts (Hakobyan+, 2017)J/MNRAS/481/566 : Properties of 333 SNe & their 269 hosts (Karapetyan+, 2018)J/MNRAS/490/718 : Properties of 109 SNe & their 104 hosts(Barkhudaryan+, 2019)http://www.sdss.org : SDSS Home Pagehttps://sne.space : The Open Supernova Cataloghttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/499/1424https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/499/1424http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/499/1424https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/499/1424https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/499/1424http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/499/1424GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/499/1424/table13 (Properties of 407 SNe and their 394 hosts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/499/1424/table13?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/499/1424/table13?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/499/1424/table13?GETtext/xml+votable180.050000true50.7458333-37.21333330.0055555555555555566/34 224 248 611 626 697 928 1677 1700-1701 1725 1796 2142 2227 2232 2251 2254 2265 2311 2324 2347 2353 2379 2391 2409 2412 2418 2569 2641 3393 4114 4401 4416 4447 4521 4577 4583 4684 4719 4807 4813 4966 4993 5004 5006 5095 5100 5115 5192 5639 5680 5975 6062 6101 6114 6178 6315 6549 6877 6936 6962 6968 7044 7091 7104 7166 7241 7369 7523 7606 7610 7659 7679 7681 7747 7783 7923 7975 8064 8169 8196 8403 8435 8479 8482 8526 8763 8927 9136 9311 9449 9468 9471 9535 9614 9640 9698 9794 9840 10203 10207 10219 10232 10379 10397 10428 10438 10563 10637 10650 10734 10767 10789 10817 10819 10858 10978 11064 11138 11158 11181 11246 11263 11280 11434 11496 11824 11939 12367 12455 12497 12585 12620 13313 13350 13399 13427 13459 13505 13514 13529 13545 13907 14009 14018 14733 14834 14882 14907 15056 15197 15548 15847 15954-15955 16584 16612 16690 16852 17152 17197 17239 17278 17340 17401 17410 17500 17614 17660 17670 17736 17741 17761 17817 18061 18081 18206 18209 18214 18296 18324-18325 18394 18735 18753 18895 19051 19084 19154 19227 19241 19283 19298 19506 19515 19554 19581 19900 19958 20014 20046 20090 20140 20237 20279 20283 20318 20358 20370 20490 20601 21041 21138 21300 21584 21857 22425 22599 22826 22963 23013 23023 23028 23077 23157 23179 23219 23294 23405 23820 23828 23916 24131 24152 24716 24733 24920 24926 24969 25078-25079 25141 25333 25344 25439 25491 25513 25615 25715 25769-25770 25850 25889 25960 25982 26117 26175 26210 26268 26271 26336 26338 26385 26392 26500 26563 26575 26584 26697 27145 27348 27367 27426 27470 27491 27512 27564 27634 27728 27738 27761 27773 27849 27918 27926 27945 27947 28035 28040 28075 28089 28112 28167 28249 28273 28294 28299 28353 28356 28368 28453 28498 28509 28529 28579 30044 30160 31218 31230 31293 31628 31881 32129 32136 32307 32338 32340 32542 32561 32569 32602 32620-32621 33225 33228 33681 34361 34492-34493 34531 34534 34540 35629 35844 36045 36131 36201 36287 36473 36662 36805 36919 37299 37429 37559 37580 37668 38664 38723 38956 38985 39627 39677 39836 39863 40252 40294 40337 40379 40906 43245 43262 43339 43855 43874 43877 44000 44005 44007 44026 44359 44660 44896 44915 45041 45418 46104 46568 46882 47014 47064 48075 48487 48665 48898 49109https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/499/1424?format=asciiOpticaldefaultJ/MNRAS/499/1424/table13Properties of 407 SNe and their 394 hostsTypeSN subclass (1)src.classcharrecnoRecord number assigned by the VizieR team.
