Observed and simulated right-bearing filament barbs. (A) Hα observation of a dextral filament with right-bearing barbs extending from the filament spine, adapted from A. A. van Ballegooijen (2005). Red plus and green minus symbols mark the positive and negative photospheric magnetic polarities, respectively, and the white arrow indicates the inferred axial-field direction. (B) Top view of the synthetic AIA 304 Å emission. The simulated prominence develops similarly oriented right-bearing barbs along its spine, reproducing the characteristic morphology of a dextral filament. The polarity symbols and white arrow schematically indicate the corresponding polarity arrangement and axial-field direction.
