Abstract | The low frequency cutoffs f ( lo ) and the observed plasma frequency f ( p ) of 176 type III radio bursts are investigated in this paper. These events are observed by the Parker Solar Probe when it is in the encounter phase from the first to the fifth orbit. The result shows that the distribution of cutoffs f ( lo ) is widely spread between 200 kHz and 1.6 MHz. While the plasma frequency f ( p ) at the spacecraft is between 50 and 250 kHz, which is almost all smaller than f ( lo ). The result also shows that the maximum probability distribution of f ( lo ) (similar to 680 kHz) is remarkably higher than that observed by Ulysses and Wind (similar to 100 kHz) in previous research. Three possible reasons, i.e., solar activity intensity, event electing criteria, and radiation attenuation effect, are also preliminarily discussed. |
