Study of Doppler velocities and their relationship with Magnetic field oscillations in the penumbra of Sunspots

Local oscillations of the Doppler Velocities in the penumbra of the sunspot AR12186 were studied. For thispurpose, the images were aligned using the Enhanced Correlation Coefficient (ECC), ECC+Rotation andthe method proposed by Griñón-Marín et al. (2020). The wavelet transform was used to extract th...
