| Abstract: | New BV light curves of the A-type W UMa star AQ Psc (P = 0.476d) have been observed and are described. A few times of minimum light are obtained and the ephemeris is improved.
The light curves are analyzed for the binary parameters with a light curve synthesis method. Combining the results with Lu
and Rucinski’s spectroscopic mass ratio we determined the masses and radii of the components: M
1 = 1.69M
⊙, M
2 = 0.38M
⊙, R
1 = 1.77R
⊙, and R
2 = 0.89R
⊙. |
