The first BVRI light curves and analysis of the short-period algol-type binary DI Hya.

MANIMANIS V.N. and NIARCHOS P.G.

Abstract (from CDS):

Complete CCD BVRI light curves of the eclipsing binary DI Hya are symmetric, with the secondary minimum markedly deeper at longer wavelengths, indicating a large temperature difference between the components. Analysis of the light curves indicates a detached near-contact system with relatively unevolved members.
