O-B stars in the FUV range from EURD onboard Minisat 01

The instrument EURD has been designed for high-sensitivity spectroscopy of diffuse radiation in the wavelength range from 350 to 1100 Å with spectral resolution of 5 Å. It is onboard Minisat 01, a Spanish satellite that was succesfully launched on April 21, 1997. After in-orbit test of all the systems of the satellite and the scientific payload, observations with EURD started in June 10. During the measurements (taken in the eclipses of each orbit) several individual stars have been detected longward of 912 Å. Essentially these are hot and bright stars emitting in the FUV part of EURD spectral range, from 912 to 1100 Å. They are carefully removed from the overall integration to avoid contamination in the spectrum of the hot component of the insterstellar medium. As a separate task, we have begun to identify these stars and study their spectra. We show an example of the results obtained and the envisaged possibilities for future research. Moreover, The spectra are compared with atmosphere models by Kurucz and with the few stellar observations made in this wavelength range.
