... According to modern views on the evolution and origin of stars, most of the stars are members of binary systems. ... After the second explosion, the pairs tend to break up and neutron stars and/or black holes fly apart. High velocities of radio pulsars are apparently largely due to this effect. ... For all possible pairs the probability of trajectory approach at small distances for the epoch, corresponding to the age of the younger pulsar have been evaluated. ... Pulsars J0543+2329 and J0528+2200. ...

... The hotter the gas, the faster they move, and the more energy each of them holds. The free ions and electrons in a plasma behave the same way. Knowing the temperature of the high atmosphere of Earth, or that of the Sun, we can calculate energies expected of ions and electrons found there. However, ions and electrons actually observed in space are often much , much more energetic, and may move at a respectable fraction of the velocity of light (300,000 km/sec or 186,000 miles/sec). ...
