Radio Observations of Stellar CMEs

Radio observations have the potential advantage to provide not only direct confirmation about the occurrence of stellar CMEs, but are also a potential tool to probe the systematic properties of stellar CMEs. I will describe the rationale behind using radio observations to probe the incidence and properties of stellar CMEs. I’ll start with a brief review of solar radio emissions related to CMEs, then switch to observational attempts to identify stellar type II bursts, which so far have resulted in no confident detections. I will step through the several assumptions made regarding stellar type II bursts and examine their astrophysical significance. I’ll then pan out to consider other possibilities in the radio domain such as type IV bursts and negative radio bursts, and end with some perspective on future opportunities for making progress in studying stellar CMEs using radio observations.
