| Abstract : | Spicules are the thin elogated resemble grass-like structures when observed at the solar limb through a high-resolution telescope in the wings of chromospheric spectral line such as Hα and Ca II lines. The on-disk counterparts of the Type II spicules are Rapid Red & Blue Excursions (RBEs & RREs). These Spicules move upward and downward and carry mass flux several times the solar wind. We study these spicules and their impact in the Transition region and various Coronal passbands along with their impact in the chromosphere when they are drained back. Our analysis employing space-time plots suggests that these spicules coexist in various tempratures at the same time, sampling from chromosphere to the corona via the transition region during their journey from the corona and vice versa, and display a distinctive parabolic path in space-time plots. Some of these spicules exhibit a prominent redshift in the transition region's spectral line, indicating that at least some of the redshift observed in this region is a result of the spicules as they descend into the chromosphere. Our results show mass cycling in the solar atmosphere through spicules and can be considered a potential candidate for balancing mass and energy losses of the corona. |
