A note concerning EZ Hya.
Beverly B. Bookmyer, Danny R. Faulkner · Publications of the Astronomical Society of the Pacific · 1978
EZ Hya is a southern W Ursae Majoris-type eclipsing binary system which undergoes complete eclipses. Primary eclipse is total with the duration of totality being about 45 minutes. Extensive photoelectric measurements obtained at Cerro Tololo Inter-American Observatory give good definition to the B and V light curves of the system. Eleven epochs of minimum light are presented. These and all other available photoelectric times of minimum light were introduced into a least-squares solution for the determination of an improved ephemeris. Key words: photometry-eclipsing binary-W UM a-type system
