Power spectrum analysis of limb and disk spicule using Hinode Ca H line broadband filter
Ehsan Tavabi
We present observations of a solar quiet region obtained using Hinode Solar Optical telescope (SOT) in Ca II H line with broadband filter taken on November 2006. We study offlimb a…
Increasing the Fine Structure Visibility of the Hinode SOT Ca II H Filtergrams
E. Tavabi, S. Koutchmy
We present the improved so-called Madmax (OMC) operator selecting maxima of convexities computed in multiple directions around each pixel rewritten in MatLab and shown to be very e…
The 3D behavior of a twisted flux tube expanding in the corona: reconnection, writhe and jets
Ehsan Tavabi, Serge Koutchmy, Ali Ajabshirizadeh
We discuss some aspects of magnetic reconnection which could help in understanding many aspects of magnetic plasma interactions. We will show that the helical structure often obser…
Contribution to the modeling of solar spicules
E. Tavabi, S. Koutchmy, A. Ajabshirizadeh
Solar limb and disc spicule quasi- periodic motions have been reported for a long time, strongly suggesting that they are oscillating. In order to clear up the origin and possibly…
A Statistical Analysis of the SOT-Hinode Observations of Solar Spicules and their Wave-like Behavior
E. Tavabi, S. Koutchmy, A. Ajabshirizadeh
We consider a first important parameter of spicules as observed above the solar visible limb: their apparent diameter as a function of the height above the limb which determines th…
