Seven New Low-Mass Eclipsing Binaries
We present the discovery of seven new low-mass eclipsing binaries, their photometric light curves, and preliminary models. This nearly doubles the available data on these systems, with only nine previously known. Once radial-velocity curves are completed, physical parameters wil= l be determined with an error of less than 2-3%, thus allowing for a rigorous examination of stellar models in the lower-main sequence. Our initial analysis seems to support the current findings that low-mass star= s have greater radii than models predict, most likely due to the presence o= f strong magnetic fields.
