Modeling solar chromospheric spicules with intense lasers

Solar spicules are small-scale jet-like structures in the lower solar atmosphere. Currently, formation of these widely distributed lacks a complete explanation. It is still unclear whether they play an essential role corona heating. Here, based on magnetohydrodynamic scaling transformation relation, we perform experiments with interaction high power laser one-dimensional sinusoidal modulated target to model spicules. We observe several spicule-like alternating polarity magnetic fields around them. Magnetohydrodynamic simulations similar parameters show detail information during spicules’ formation. The results suggest that so-called strong pulse can lead reconnection process may also part and additional heating brightening phenomena.
