cds-question@unistra.frgalaxiesmetallicitygalaxy-kinematicsWe analyse radial stellar metallicity and kinematic profiles out to 1R_e_ in 244 CALIFA galaxies ranging from morphological type E to Sd, to study the evolutionary mechanisms of stellar population gradients. We find that linear metallicity gradients exhibit a clear correlation with galaxy morphological type - with early-type galaxies showing the steepest gradients. We show that the metallicity gradients simply reflect the local mass-metallicity relation within a galaxy. This suggests that the radial stellar population distribution within a galaxy's effective radius is primarily a result of the in situ local star formation history. In this simple picture, the dynamically derived stellar surface mass density gradient directly predicts the metallicity gradient of a galaxy. We show that this correlation and its scatter can be reproduced entirely by using independent empirical galaxy structural and chemical scaling relations. Using Schwarzschild dynamical models, we also explore the link between a galaxy's local stellar populations and their orbital structures. We find that galaxies' angular momentum and metallicity gradients show no obvious causal link. This suggests that metallicity gradients in the inner disc are not strongly shaped by radial migration, which is confirmed by the lack of correlation between the metallicity gradients and observable probes of radial migration in the galaxies, such as bars and spiral arms. Finally, we find that galaxies with positive metallicity gradients become increasingly common towards low mass and late morphological types - consistent with stellar feedback more efficiently modifying the baryon cycle in the central regions of these galaxies.2019MNRAS.483.1862Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/483/1862CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/594/A36 : CALIFA Survey DR3 list of galaxies (Sanchez+, 2016)J/A+A/597/A48 : Stellar kinematics in CALIFA survey (Falcon-Barroso+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/483/1862https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/483/1862http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/483/1862https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/483/1862https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/483/1862http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/483/1862GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/483/1862/tablea1 (Galaxies metallicity gradients and general properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/483/1862/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/483/1862/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/483/1862/tablea1?GETtext/xml+votable180.050000true118.846788126.74112190.0055555555555555566/545 552 554 620 738 909 949 975 2206 2228 2248 2251 2272-2274 2276 2290 2641 4167 4178 4342 4445 4477 4511 4654 4801 4813 4829 4840 4843 4850 4950 4957 5028 5298 5332 5505 5533 5593 5889 6214 6216 6240-6241 6261 6270 6366 7214 7340 7560 7589 7824 8477 8492 8498 8522 8536 8552 8562-8563 8656 8743 8883 9124 9187 9216 9220 9381 9470-9471 9622 9628 9630 9695 9718 9812 9873 9875 9882-9883 9885 9891 9946 9974 10111 10183 10200 10220-10221 10280 10380-10381 10401 10515 10566 10583 10588 10595 10612 10627-10629 10705 10739-10740 10773 10778 11070 11112 11164 11196 11290 11314 11369 11372 11377 11383 11392 11396 11435 11443 11525 11544 11832 11905 11944 12532 12709 13316 13380-13381 13426 13529 15002 16007 16702 16788 17233-17234 17237 17350 17398 17486 17499 17758 17819 17912 17998 18008 18069 18071 18173 18302 18383 18523 18775 18779 18781 18790 18800 18854 18931-18932 18934-18935 18941 19073 19108 19227 19260 19387 19458 19487 19489 19508 19536-19538 19618 19642 19696 19749 19848 19939 19954 19981 19984 19996 20020 20023 20031-20033 20193 20254 20279 20417 20429 22361 22364 22652 22737 22741 23273 23337 23405 26495 27133 27608 28430 28458 28513 28579 28617 28639 29973 31546 31628 31642-31643 31688-31689 31736-31737 32462 32471 32478 32482 32555 32559 48880 49130 49150https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/483/1862?format=asciidefaultJ/MNRAS/483/1862/tablea1Galaxies metallicity gradients and general propertiesSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
