In this seminar, I will talk about newly forming stars like our Sun, which drive supersonic jets/outflows whilst they accrete material from their circumstellar disks. I will present our pathfinding observations of the very long wavelength radio emission from these jets using the Giant Metrewave Radio Telescope (GMRT) at 50 and 90 cm and the Low Frequency Array (LOFAR) at 2 m - the first successful detections of jets from young stars at such long wavelengths. Although radio emission from such objects typically arises from thermal free-free radiation, I will show a few cases where synchrotron emission has been detected and believed to arise from shocks in the outflows - suggesting the possibility of low energy cosmic rays being generated by young Sun-like stars.
