Spectrophotometric observations with the help of space astrophysical observatories ORION 1 and ORION 2

Abstract

A short description of optical systems of space astrophysical observatories Orion 1 and Orion 2 is presented. With the help of these observatory-spectrographs, the short wavelength spectrograms, up to 2000 angstroms, of individual stars have been obtained. A concise resume of main scientific results derived from these spectrograms are presented as well.
