cds-question@unistra.frgalaxiesstellar-massesgalaxy-classification-systemsWe use the Spitzer Photometry and Accurate Rotation Curves (SPARC) database to study the relation between the central surface density of stars {Sigma}_*_(0) and dynamical mass {Sigma}_dyn_(0) in 135 disk galaxies (S0 to dIrr). We find that {Sigma}_dyn_(0) correlates tightly with {Sigma}_*_(0) over 4dex. This central density relation can be described by a double power law. High surface brightness galaxies are consistent with a 1:1 relation, suggesting that they are self-gravitating and baryon dominated in the inner parts. Low surface brightness (LSB) galaxies systematically deviate from the 1:1 line, indicating that the dark matter contribution progressively increases but remains tightly coupled to the stellar one. The observed scatter is small (~0.2dex) and largely driven by observational uncertainties. The residuals show no correlations with other galaxy properties like stellar mass, size, or gas fraction.2016ApJ...827L..19Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/827/L19CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/152/157 : Mass models for 175 disk galaxies with SPARC (Lelli+, 2016)J/A+A/566/A71 : HI study of 18 nearby dwarf galaxies (Lelli+, 2014)J/MNRAS/433/L30 : Velocity gradient & brightness in disc galaxies (Lelli+ 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/827/L19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/827/L19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/827/L19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/827/L19https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/827/L19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/827/L19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/827/L19/figure2 (Central dynamical surface density versus central stellar surface density and total stellar mass)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/827/L19/figure2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/827/L19/figure2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/827/L19/figure2?GETtext/xml+votable180.050000true73.279583367.09916670.0055555555555555566/975 1007 1114 1561 2351 2383 2866 3436 3511 3519 4511 4522 4534 4554 4650 5067 5124 5129 5168 5174 5230 5329 5500 5581 5584 5587 5589 5591 5594 5596 5599 5623 5628-5629 5631 5636 5669 5710 5751 5827 5956 5967 5975 5982 6623 7132 7241 7303 7523 7602 7624 7743 7882 7946 7957 8552 8557 9097 9463 9855 10286 10475 10511 10637 10662 10809 10817 10841 10881 10908 10910 10924-10925 10927 10930 10935 10976 10990-10991 11000 11006 11019 11092 11127 11389 11448 11566 11639 11696 12570 13489 13522 13668 15551 15592 15594 16016 16441 16519 16595 16701 17165 17753 18315 18378 19570 20353 20438 24952 26106 27030 28077 28087 28107 28149 28230 28259 28261 28346 28463 28496 28535 28637 32231 33435 33589 35514 35536 35746 36974 38846 40531 43972https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/827/L19?format=asciiOpticaldefaultJ/ApJ/827/L19/figure2Central dynamical surface density versus central stellar surface density and total stellar massrecnoRecord number assigned by the VizieR team.
