The Soyuz-13 - Orion-2 space observatory
Abstract
The large-scale astrophysical experiment conducted aboard the Orion-2 observatory (carried by Soyuz-13) in December 1973 is described. Particular attention is given to the design and operating principle of the observatory, its installation on Soyuz-13, and stellar observations with the participation of the cosmonauts. The scientific results obtained are discussed, with emphasis on hot and cold stars, the Mg II 2800 doublet in stellar spectra, nebulae in the ultraviolet, circumstellar nebulae, the spectral classification of stars according to UV observations, and the physical parameters of stellar atmospheres.
