cds-question@unistra.frgalaxiesstar-forming-regionsgalaxy-classification-systemsvisible-astronomyWe explore the effects of tidal interactions on star formation (SF) by analysing a sample of CALIFA survey galaxies. The sample consists of tidally and non-tidally perturbed galaxies whose star-forming regions are paired at the closest stellar mass surface densities, even between the same galaxy types. The regions are then compared, both on the resolved star-formation main sequence (SFMS) plane and in annular property profiles. Star-forming regions in tidally perturbed galaxies exhibit flatter SFMS slopes compared to star-forming regions in non-tidally perturbed galaxies. Despite the fact that the annular profiles show star-forming regions in tidally perturbed galaxies as being mostly older, their SF properties are never reduced against those of non-tidally perturbed galaxies. Star-forming regions in non-tidally perturbed galaxies are better candidates for SF suppression (quenching). The lowered SF with increasing stellar mass density in tidally perturbed galaxies may suggest a lower dependence of SF on stellar mass. Though the SFMS slopes, either flatter or steeper, are found independent of stellar mass density, the effect of global stellar mass cannot be ignored when distinguishing between galaxy types. Since a phenomenon or property other than local/global stellar mass may be taking part in the modulation of SF, the integrated SF properties are related to the tidal perturbation parameter. We find weak, but detectable, positive correlations for perturbed galaxies suggesting that tidal perturbations induced by close companions increase the gas accretion rates of these objects.2020MNRAS.499.4370Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/499/4370CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/420/873 : Properties of isolated disk galaxies (Varela+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/499/4370https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/499/4370http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/499/4370https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/499/4370https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/499/4370http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/499/4370GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/499/4370/tablea1 (Fundamental properties for control (f<-4.5) and perturbed (f>=-4.5) objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/499/4370/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/499/4370/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/499/4370/tablea1?GETtext/xml+votable180.050000true353.101734215.84783890.0055555555555555566/43 56 568 626 721 733 908 949 995 2206 2251 2254 2272 2274 2290 2641 4053 4178 4279 4342 4445 4454 4507 4511 4704 4712 4719 4753 4801 4806 4840 4843-4844 4850 4912 4950 5024 5028 5241 5533 5579 6087 6216 6342 6362 6366 6448 6547 7214 7309 7340 7442 7559 7572 7844 8164 8331 8458 8480 8492 8498 8522 8552 8563 8621 8728 8752 8825 8883 8900 8919 8921-8922 8973 9098 9101 9124 9381 9718 9798 9875 9883 9974 10025 10113 10220-10221 10280 10380-10381 10414 10422 10448 10485 10511 10515 10518-10519 10570 10577 10588 10595 10609 10612 10621 10627-10629 10661-10662 10674 10711 10727 10739 10778 10987 11070 11112 11196 11272 11290 11374 11377 11396 11433 11451 11544 11777 11789 11793 11800 11832 11944 12306 13316 15004 16787 17234 17238 17350 17398 17486 17499 17509 17511 17661 17745 17747 17761 17819 18069 18071 18173 18242 18300 18383 18523 18775 18779 18781 18800 18854 18932 18934 18941 19227 19267 19458 19487 19508 19538 19593 19618 19749 19848 19954 19983 19996-19997 20020 20023 20031 20040 20193 20279 20417 20429 22364 22652 22742 23051 23076 23182 23204 23273 23337 26108 27559 27567 27719 27748 28458 28513 28522 28617 28639 29973 31688 36604 36733 36793 36857 49150https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/499/4370?format=asciiOpticaldefaultJ/MNRAS/499/4370/tablea1Fundamental properties for control (f<-4.5) and perturbed (f>=-4.5) objectsSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
