Indian Institute of Astrophysics Abstract Type : Poster Abstract Category : Sun and the Solar System Abstract : The magnetic helicity of small-scale fields on the Sun shows an opposite hemispherical pattern (in sign) than that of the large-scale magnetic fields (containing sunspots). Here, using Doppler and magnetic data from the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO), we examine if the above pattern is caused by fluid motion around magnetic structures - we derive horizontal velicities estimated through local correlation tracking. We derive kinetic helicity of fluid motion and study its connection to the small-scale magnetic helicity. |
