Precessing jets in the Red Rectangle?
Abstract
It is proposed that the central object in the 'Red Rectangle', a peculiar infrared source with a biconical reflection nebula, may be emitting oppositely-directed relativistic jets of gas which precess in a manner similar to that invoked to explain the anomalous emission lines in SS 433. The broad red spectral line in the light of the nebula may be interpreted as H alpha emission from the jets broadened by the high velocity, and the biconical shape as indicating that the nebula consists of material thrown out in the jets.
