A novel approach to identify resonant MHD wave modes in solar pores and sunspot umbrae: B-ω analysis

The umbral regions of sunspots and pores in the solar photosphere are generally dominated by 3~mHz oscillations, which are due to p-modes penetrating the magnetic region. In these locations, wave power is also significantly reduced with respect to the quiet Sun. However, here we study a pore where the power... Show more
