| Description |
Pulsars are rapidly rotating and heavily magnetized neutron stars, city-sized objects that have masses that are greater than that of our Sun. They are visible through their radio emission in the form of pulses that reach the observatory when the beam sweeps past our line of sight. However, the physical processes that make pulsars shine at radio frequencies are still poorly understood. Most of the pulsars seem to become dimmer with increasing radio frequency in a steady manner, but a select few (about 20 per cent of the best-studied ones) show bumps or curves in their spectra. The latter ones become first brighter and then fainter with increasing frequency when observed from Earth. In this project, we try to understand the exact behaviour of 26 of those odd sources. We do this because we want to understand why they are not like the others that have smoothly decreasing brightness.
