Since their discovery, type II spicules are thought to be one of the
prime candidates behind keeping the lower corona at million degrees
Kelvin, as well as responsible for supplying mass to the lower corona.
One way to understand such mass supply is through analysing the
asymmetric spectral line profile. In this work, we simulate the flow of
cold plasma in the coronal magnetic structure, and find that shock can
produce a rise in temperature. For further analysis, synthetic coronal
spectral lines are produced from the simulated data through forward
modelling. Studying the red-blue asymmetric nature of this reveal that
spicules are indeed capable of contributing mass to the corona
significantly. We also analyse the earlier theoretical study of Klimchuk(2012) and find that the underlying simplified assumptions in that prevents one to conclude in favour of type II spicules, thereby
simultaneously affecting the conclusions of the follow-up observational
results as well.
