Is the eclipsing binary EU Hydrae a semi-detached system?
VIVEKANANDA RAO P., SARMA M.B.K. and ABHYANKAR K.D.
Abstract (from CDS):
The V and B light curves of the Algol type eclipsing binary EU Hydrae (EU Hya) obtained during 1973-74 and 1977 with the 1.2m telescope of the Japal-Rangapur Observatory were analyzed for elements using Wilson-Devinney synthetic light curve method. The results suggest that EU Hya is a semi detached system with a photometric mass ratio of 0.212. The primary component is found to be an F2V (6900 K) and the secondary component is an evolved star of K0-4V-IV (4152 K) spectral types.
