Using the Tillinghast Reflector Echelle Spectrograph (TRES) and the Transiting Exoplanet Survey Satellite (TESS), astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) have detected an M-dwarf companion to a nearby M-dwarf star designated G 68-34. The finding, published April 5 on the pre-print server arXiv, identifies G 68-34 a double-lined M-dwarf eclipsing binary.
