| with a light-travel time analysis of eclipse timings by Bakis et al. | Bks2005 | |
| XY Leo. Spectral type of resolved companion estimated at K6V. | Ruc2007 | |
| Multiple system including contact binary XY Leo. Pribulla & Rucinski | ||
| (2006) estimate the mass of the contact pair at 1.378 Msun and the | Pbl2006 | |
| minimum mass of the wider component at 1.00 Msun. |
