The maximum circular velocity (V_circ_^max^) and circular velocity at the half-light radius (V_circ_(Re^maj^)) both scale linearly with the stellar second velocity moment {sigma}_e_^2^=&lt;V^2^+{sigma}^2^&gt; within the half-light isophote, following V_circ_^max^~1.72{sigma}_e_ (7% error) and V_circ_(Re^maj^)~1.62{sigma}_e_ (7% error). CVC shapes (rising, flat, declining) correlate strongly with structural and stellar population properties: declining curves dominate in massive, early-type, bulge-dominated galaxies with old, metal-rich stars and early quenching, while rising CVCs prevail in disk-dominated systems with younger stellar populations and ongoing star formation. Using a unified bulge-disk-halo model, we predict CVC shapes with minimal bias, identifying three governing parameters: bulge-to-total mass ratio (B/T), dark matter fraction within Re, and bulge Sersic index. The distribution of CVC shapes across the mass-size plane reflects evolutionary pathways driven by (i) in situ star formation (spurring bulge growth) and (ii) dry mergers. This establishes CVC morphology as a diagnostic for galaxy evolution, linking dynamical signatures to structural and stellar population histories.</description><source format="bibcode">2025ApJS..280...55Z</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/280/55</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/371/703">J/MNRAS/371/703 : MILES library of empirical spectra (Sanchez-Blazquez+, 2006)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/413/813">J/MNRAS/413/813 : ATLAS3D project.
