Photometry of cool stars detected in extreme-ultraviolet (EUV) all-sky surveys.
CUTISPOTO G., PALLAVICINI R., KUERSTER M. and RODONO M.
Abstract (from CDS):
We present high-precision UBV(RI)c photometry for a small sample of cool stars detected at EUV wavelengths by the ROSAT WFC and/or the EUVE all-sky survey. Four out of the five stars observed are variable and one of them is an eclipsing binary. Amplitudes up to 0.38 magnitudes in the V band have been observed and clear colour variations have been found. We have computed the photometric periods and deduced approximate spectral classifications and distances.
