A new detached K7 dwarf eclipsing binary system

We present an analysis of a new, detached, double-lined eclipsing binary system with K7 Ve components, discovered as part of the University of New South Wales (UNSW) Extrasolar Planet Search. The object is significant in that only six other binary systems are known with comparable or lower mass. Such systems offer important tests of mass‐radius theoretical models. Follow-up photometry and spectroscopy were obtained with the 40-inch and 2.3-m telescopes at Siding Spring Observatory (SSO), respectively. An estimate of the radial velocity amplitude from spectral absorption features, combined with the orbital inclination (83.5 ◦ )
