.orgWe have found that in the absorptionline spectra of two quasars, 0237-233 and HE 1122-1648 there are a large number of common lines in the observed frame (earth frame). The number of common lines in the interval 3716-4116 Å is 64 while the expected number from the chance– coincidence theory is only 49.7 ± 3.8.
The redshift hypothesis can not explain these coincidences. On the other hand, these coincidences can be readily understood on the basis of a theory of quasars proposed by us (1975, ApSS 37, L1; 1977, ApSS 46,443; 1979 Phys.Canada 35,11) according to which a quasar is a star in which the surface plasma is undergoing rapid radial expansion giving rise to population inversion and laser action in some of the atomic species.
The assumption of the ejection of matter from quasars at high speed is supported from the fact that the widths of emission spectral lines observed in quasars are typically of the order of 2000 - 4000 km/sec. The ejected matter can form a nebulosity around the quasar or dissipate into space. Laser action is enhanced if the hot plasma contacts this colder gas. No redshifts are needed. This model is called the plasmalaser star (PLAST) model. Most of the observational evidence on quasars either supports this theory or is consistent with it.
If we consider two stars which belong to the same spectral class or to very neighbouring spectral classes, for example two A2 type stars or one A2 type star and the other A3 type star, then they have very many common absorption lines. This arises because in the two cases the plasma where the absorption is occurring is very similar in the two cases. In our theory of quasars the absorption is occurring in the extended atmosphere of a star, much like a shell star. The coincidences between the wavelength of lines in 1122-1648 and 0237-233 is occurring because the shells of these two stars are quite similar.
