Abstract

The existence of novel electrostatic solitary pulses in an electron–positron plasmas with two distinct groups of positrons is demonstrated. It is found that the soliton potential can assume both the rarefactive and compressive polarities. The results might be useful in understanding the properties of localized disturbances in astrophysical plasmas.
