cds-question@unistra.frgalaxiesgalaxy-classification-systemsvisible-astronomyBars inhabit the majority of local-Universe disc galaxies and may be important drivers of galaxy evolution through the redistribution of gas and angular momentum within discs. We investigate the star formation and gas properties of bars in galaxies spanning a wide range of masses, environments, and star formation rates using the Mapping Nearby Galaxies at APO galaxy survey. Using a robustly defined sample of 684 barred galaxies, we find that fractional (or scaled) bar length correlates with the host's offset from the star formation main sequence. Considering the morphology of the H{alpha} emission we separate barred galaxies into different categories, including barred, ringed, and central configurations, together with H{alpha} detected at the ends of a bar. We find that only low-mass galaxies host star formation along their bars, and that this is located predominantly at the leading edge of the bar itself. Our results are supported by recent simulations of massive galaxies, which show that the position of star formation within a bar is regulated by a combination of shear forces, turbulence, and gas flows. We conclude that the physical properties of a bar are mostly governed by the existing stellar mass of the host galaxy, but that they also play an important role in the galaxy's ongoing star formation.2020MNRAS.495.4158Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/495/4158CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/154/86 : MaNGA catalog, DR15 (Wake+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/495/4158https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/495/4158http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/495/4158https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/495/4158https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/495/4158http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/495/4158GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/495/4158/tablea3 (Additional data for all 684 galaxies in the barred galaxy sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/4158/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/4158/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/4158/tablea3?GETtext/xml+votable180.050000true139.647666144.59690190.0055555555555555566/1 554 640 4138 4661 4705 4730 4733 4747-4748 4758-4759 4764 4784 4794-4795 4817 4819 4826-4829 4845 4850 4854 4858 4861 4906 4914 4919-4920 4960 4962 4964 4992 4994 5000 5117 5351 5372 5471 5530 5552 5556 5561 5563-5565 5577 5594 5600 5604 5607 5615 5620 5626 5629 5638 5671 5680 5688 5751-5752 5756 5791 5798 5800 5816 5824 5830 5840 5844 5862 5865 5867 5888 5904 5907 5918 5923 5929 5939 5954-5955 5957-5959 5967-5968 5970 5972 5976 5979 6212 6214 6217 6220 6223 6226 6233 6241 6245 6247 6250 6260 6262-6263 6385 6396 6445 6456 6462 6528 6532 6534 6537 6539 6541 6544-6545 6564 6570-6571 6574 6578-6579 6582-6584 6586-6587 6589 6595 6599 6601 6603-6606 6608 6624-6625 6627 6636-6637 6639 6641 6649 6651 6654-6655 6740-6741 6930 6932 7186 7226 7231-7232 7314-7315 7317 7320-7321 7330 7339 7344 7354 7363 7368-7370 8575 8665 8679 8700 8702 9029 9031 9037 9043 9047 9065 9069 9071 9084 9161 9169 9231 9242 9249 9252 9258 9260-9261 9265 9267 9279 9345 9354 9356 9359 9366-9367 9369 9371 9374 9392 9400 9418 9459 9462 9465 9468 9470-9471 9482 9484 9486 9505 9509 9516 9601 9605-9606 9632 9638 9642 9646-9647 9785 9807 9809 9811 9813-9814 9829-9830 9833 9840 9878 9881 9885-9886 9891 9894 9898 9900-9902 9909 9921 9923 9931 9933 9936 9943 9963 9985-9986 9990 9998 10018 10022 10024 10062-10063 10085 10095 10099 10104 10112 10120 10194 10247 10256 10261-10262 10267 10269-10270 10291 10293 10295 10306 10349-10350 10373 10376 10378-10380 10382 10390 10398-10400 10417 10428 10430 10437-10438 10442-10443 10451 10453 10455 10460 10484 10547-10548 10551 10581 10593 10602 10621 10636 10651-10652 10658-10659 10662-10663 10668 10673 10675-10676 10695 10700 10702 10706 10713 10769 10775 10872 10880 10893 10921 10927 10932 10950 10955-10956 11023 11041 11043-11045 11265 11268-11269 11282 11297 11300-11301 11312-11313 11315 11323 11348-11350 11381 11384 11396 11399 11406 11410 11416 11427 11432-11433 12399 17750 17756 18066 18069-18070 18075 18077 18303 18780 19097-19099 19120 23047 23051 23147 23181 23194-23196 23198 23205 23208-23209 23211-23212 23214 23216 23233 27263 27314 28126-28127 28149 28271 28282 28362-28363 28365 28630 28636 28638 30043 32509 32680https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/495/4158?format=asciiOpticaldefaultJ/MNRAS/495/4158/tablea3Additional data for all 684 galaxies in the barred galaxy sampleSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
