Abstract (from CDS):

We report the confirmation of three X-ray and radio stars at high galactic latitudes as a by-product of a search originally aiming to find new microquasars. The objects are the late type, optically bright stars HD 135743, CD-2412231 and HD 220338. Interestingly, the last of them has displayed, on time scales of years, what could be considered as a radio flaring behaviour and deserves follow up. The observational evidence gathered, at radio and optical wavelengths, suggests that these objects are likely new chromospherically active stars relatively close to the Sun.
