QPPs in stellar and coronal loops
Fast sausage and standing slow modes in coronal loops are the most studied oscillation modes because their compressibility makes them susceptible to being observed. By performing magnetohydrodynamic numerical simulations, we analyse the capability of different types of disturbances associated with typical fluctuations in solar corona energy to generate these modes.
We investigate the modulation depth of gyrosynchrotron emission produced by these fast sausage modes. We analysed the synthetic emission from coronal and stellar loops and found that finite-amplitude sausage modes have the potential to generate the observed deep modulation depths.
