Abstract: Coronal mass ejections (CMEs) are the most explosive manifestations of stellar magnetic activity. In the solar case, CMEs and flares are associated with each other and this association increases with increasing flaring energy, reaching 100% for high energies. But does this hold true for other stars? Stellar flares with various strengths have been observed on numerous occasions at radio, optical, UV and X-ray wavelengths. This is not the case for CMEs. To date there are very few stellar CMEs detected. In this talk I will discuss some recent results from CME studies in the optical and radio domains, and our ongoing program to detect CMEs, particularly at LOFAR frequencies.
