We find that these type II bursts would remain within the frequency range of LOFAR for a maximum of 20–30 minutes post-eruption for the polar CMEs (50 minutes for second harmonics). We show that the length of time these events remain above the ionospheric cutoff is not necessarily dependent on the stellar magnetic cycle, but more on the eruption location relative to the stellar magnetic field. Stellar type II radio bursts are expected to emit below 450 MHz, similarly to their solar counterparts. These stellar eruptions have proven to be elusive, although a promising approach to detect and characterize these phenomena are low-frequency radio observations of potential type II bursts as CME-induced shocks propagate through the stellar corona. We use three separate epochs from 2008, 2011, and 2013, and estimate the radio emission frequencies associated with these events. We simulate possible stellar coronal mass ejection (CME) scenarios over the magnetic cycle of Eridani (18 Eridani HD 22049).
