Laser star model of quasars

From Free net encyclopedia

The laser star hypothesis is a hypothesis put forward by the physicist Y. P. Varshni in the early to mid 1970s in response to several developments in astrophysical and earth-based research, and his belief that the existing body of work on quasars, or "quasi stellar objects," suffered fundamental difficulties. It states that many, if not all, quasars are instead stars which are producing natural lasing. This model is contradicted by a number of astrophysical observations which have leas to the astrophysical science community understanding that quasars are distant AGN.

Observations that contradict the laser star hypothesis include gravitational lensing, where multiple images of the same quasar are seem around an intervening galaxy, and the correlation of absorption lines in quasar spectra which correspond to identified intervening systems.
