β = (v/c)²: A Two-Level Kinematic Indicator of Galaxy State

Preprint version 2.0.0. We investigate the kinematic parameter β = (v/c)² as a two-level indicator of galaxy state. On a sample of ALFALFA α.40 × SDSS DR7 × galSpecExtra DR8 (N = 9724), we confirm that globally β anti-correlates with gas fraction (r = −0.347, p < 10⁻²⁷²) and posi...
