Brown dwarf in a dynamical-tide regime detected by WASP survey

European astronomers have discovered a new transiting brown dwarf in a dynamical-tide regime as part of the Wide Angle Search for Planets (WASP) survey. The newly found object, designated WASP-128b, orbits its host on a close orbit—the measured stellar rotation rate places it in a regime where tidal interaction is dominated by dynamical tides. The finding is detailed in a paper published July 19 on arXiv.org.
