The trace-back motion study and trajectory analysis of 529 CP stars, 392 known runaways, 948 runaway OB candidates and 607 pulsars show an identification of number of promising candidates (single star or pulsar-star pair) that ejected from one of these clusters either by dynamical ejection or a supernova event and supports the idea suggesting that the chain is formed by feedback-driven gas compression.
