Besides a red dwarf, the system also includes one of the first exoplanets to be discovered, Tau Boötis b, located in 1996. It hosts at least 2 stellar components. The exoplanet Tau Boötes b orbits the star Tau Boötes, which is indicated by the red circle. Scientists also were able to use another imaging technique that works only if the planet is sufficiently far away from its host star. The primary star should be easily visible to the unaided eye under dark skies. Tau Boötis B is a Binary or Multiple star system. Note that the system is a multiple star system. Tau Boötis B is a M3V C main sequence star based on the spectral type that was recorded in Simbad at Strasbourg University. “We now are applying our effective new infrared technique to several other nontransiting planets orbiting stars near the Sun,” Dr Bender said. Tau Boötis B is not part of the Bootes constellation outline but is within the borders of the constellation. Near-IR Direct Detection of Water Vapor in Tau Boötis b.

The planetary system tau Boo hosts at least one planet. If the R.A. is positive then its eastwards. It is a so-called hot-Jupiter that orbits closely around its host star every 3 days 7.5 hours. However, significant portions of the population of extrasolar planets do not fit either of these criteria, and there had not been a way to discover information about the atmospheres of these planets. Tau Boötis b is an extrasolar planet. It was the first planet to be identified orbiting its parent star, Tau Boötis, located 50 light-years away. Such a signal is likely the result of charged particles from the stars being warped in their paths past the mighty world. Sua descoberta foi anunciada em 1996 por Geoffrey Marcy e R. Paul Butler.
