英文摘要New multicolour photometric observations were carried out on 22 nights in three observation missions between 2015 October and 2016 February for eclipsing binary HIP 7666. High- and low-resolution spectroscopic observations were also carried out in the winters of 2015, 2016, and 2019, respectively. The fully phase-covered light curves and radial velocity curves are presented. All times of light minima are used to calculate the orbital period [2.372 2200(4) d] and new ephemerides. The photometric solution and stellar physical parameters are derived, showing that HIP 7666 is a detached binary with the absolute parameters M-1 = 1.53(3) M-circle dot, R-1 = 2.08(2) R-circle dot, log L-1/L-circle dot = 0.99(3), log g(1) = 3.98(2), M-boll = 2.26(8), T-eff,(1) = 7100(100) K for the primary, and M-2 = 1.23(3) M-circle dot, R-2 = 1.06(2) R-circle dot, log L-2/L-circle dot = 0.13(4), log g(2) = 4.47(2), M-bo12 = 4.4(1), T-eff,(2 )= 6029(67) K for the secondary. The age of 1.69 Gyr and 1.755 Gyr are estimated from PARSEC isochrones and MESA evolutionary tracks, respectively. In Herzsprung-Russell (H-R) diagram, the primary component has evolved to the late stages, while the secondary still locates at the early stages of the main sequence. Frequency analysis yields three frequencies of f(1) = 24.631(4) cd(-1),f(2) = 21.193(1) cd(-1), and f(3) = 28.07(7) cd(-1). Comparisons between models and observations suggest that the primary component is most likely a delta-mode non-radial delta Scuti oscillator.
