Photometry of an active Algol-type binary HP Aur.
Abstract
The short period Algol-type binary HP Aur has been studied on the basis of UBV photometric observations. Its color indexes were found to be (U - B) = 0.14, (B - V) = 0.70, and light curves show nonsymmetrical and obvious photometric disturbances. Autoregressive spectral analysis and harmonic analysis for its light variations were made. The results indicate its brightness variations have the multiplet quasi-periods and low amplitudes. Its photometric solutions have been obtained using the Wilson-Devinney method. Its mass ratio is 0.5631, orbital inclination is 85.0 and it is a detached system. Its basic model has been discussed briefly.
