A Unique Low-mass-ratio Contact Eclipsing Binary System under the Period Cutoff

A Unique Low-mass-ratio Contact Eclipsing Binary System under the Period Cutoff

We present a multiband photometric analysis of CRTS J163819.6+03485, the first low-mass-ratio contact binary system with a period of 0.2053321 day under the contact binary period limit. The unprecedented combination of mass ratio and period makes this system unique for eclipsing binary (EB) research...
