Generation of Alfvén Waves by Small-Scale Magnetic Reconnection in Solar Spicules
Alfvén waves dissipation is an extensively studied mechanism for the coronal heating problem. These waves can be generated by magnetic reconnection and propagated along the reconnected field lines. Here, we study the generation of Alfvén waves at the presence of both steady flow and sheared magnetic field in the longitudinally density stratified of solar spicules. The initial flow is assumed to...

متن کاملHough Transform to Study the Magnetic Confinement of Solar Spicules
One of the important parameters of the ubiquitous spicules rising intermittently above the surface of the Sun is the variation of spicule spline orientation with respect to the solar coordinates, presumably reflecting the focusing of ejection by the coronal magnetic field. Here we first use a method of tracing limb spicules using a combination of second derivative operators in multiple directio...
متن کاملThe Magnetic Field of Solar Spicules
Determining the magnetic field of solar spicules is vital for developing adequate models of these plasma jets, which are thought to play a key role in the thermal, dynamic, and magnetic structure of the chromosphere. Here we report on magnetic spicule properties in a very quiet region of the off-limb solar atmosphere, as inferred from new spectropolarimetric observations in the He I 10830 Å tri...
متن کاملMagnetic Reconnection in Sheared Solar Magnetic Arcades
The evolution of solar magnetic arcades is investigated with the use of MHD simulations imposing resistivity on sheared magnetic elds. It is found that there is a critical amount of shear, over which magnetic reconnection can take place in an arcade-like eld geometry to create a magnetic island. The process leading to reconnection cannot be solely attributed to a tearing instability, but rather...
