Popis: | Utilizing ALFALFA HI data, we investigate the relationship between specific star formation rate (sSFR) and halo spin across various star-forming galaxies. Our analysis reveals no significant correlation between sSFR and halo spin, irrespective of the galactic environment. Previous research suggests that high-spin halos tend to harbor extended, low-density stellar distributions due to suppressed gas cooling and star formation. However, unlike galaxy size and density, sSFR may primarily reflect the current star-forming state rather than long-term history, indicating potential independence from halo spin.
