Spicules and prominences: their life together .
Abstract
Spicules (fibrils against the disk) and filament channels are fundamental parts of the solar chromosphere. What happens to fibrils that are captured in a filament channel? It has been suggested that "fibrils are associated with spicules" and that filaments and fibrils are different in nature. However, those fibrils and filaments living together in the same filament channel have to follow the same magnetic topology rules. This allows us to trace the structure of the magnetic field in the filament channel at the chromospheric level. Spicules/fibrils inside a filament channel represent a basement structure of the whole building of a filament and filament cavity above. Therefore, understanding the magnetic pattern of spicules/fibrils in the filament environment will help construct correct filament/prominence models and resolve some old filament puzzles, such as the bright rim observed near the feet of filaments/prominences.
