Scientific paper
UVSTAR, UltraViolet Spectrograph Telescope for Astronomical Research, operates in the 500-1250 Å wave-band at 1 to 3 Å resolution. Here we report on the EUV and FUV observations of the B2 II star Adara, the brightest EUV source in the sky, obtained by UVSTAR during the STS 69 and STS 95 missions. The discussion concerns 1) wavelength and flux calibration, 2) short term time variability of selected spectral features, 3) comparison with previous measurements in the EUV band and 4) comparison with model atmospheres.
