de Miguel , Enrique

The star shows total eclipses, the CV magnitude of the secondary eclipse being 11.229. The light curve exhibits reflection effect. Assuming the orbital to be circular with inclination i =90º, the radii of the primary (1) and secondary (2) stars are approximately given by R1/a= 0.28 and R2/a= 0.09, with a being the binary separation. The distance is estimated as 4.03+/- 0.66 kpc, according to Russeil et al., A&A 470, 161 (2007).
