Cycle dependence of helioseismic oscillations above the acoustic cut-off frequency
Dmitrii Kolotkov, Anne-Marie Broomhall, Laura Jade Millson +1
Helioseismic and recent asteroseismic observations reveal fine structure in the power spectrum with alternating peaks and troughs above the acoustic cut-off frequency. This structu…

Investigating magnetic activity cycles in solar-like oscillators using asteroseismic data from the K2 mission
Gleb Berloff, Anne-Marie Broomhall, George T. Hookway +3
We present the results of an investigation into the possible presence of magnetic activity cycles in stars observed in two observational campaigns by the K2 mission. This study was…

Latitudinal dependence of variations in the frequencies of solar oscillations above the acoustic cut-off
Laura Jade Millson, Anne-Marie Broomhall, Tishtrya Mehta
At high frequencies beyond the acoustic cut-off, a peak-like structure is visible in the solar power spectrum. Known as the pseudo-modes, their frequencies have been shown to vary…
